When is it Safe to Have Unprotected Sex?

safe-time-to-have-unprotected-sexIn the comment board for my article, “What Does Your Vagina Discharge Tell You,” one question was asked more than once: “If I have unprotected sex on x and y days, can I get pregnant?”

Having unprotected sex can be quite enjoyable. But it does come with a consequence – a potentially significant one, if you’re not prepared to have and raise a child.

So if you choose the Fertility Awareness Method for natural birth control, you need to become familiar with your menstrual cycles and be diligent in determining when are the safest days for unprotected sex.

Generally, there are four safe windows:

1. First 5 Days

You’re safe the first 5 days of your menstrual cycle if you ovulated during the previous cycle, which can be identified by observing clear and slippery egg white-like vaginal discharge, or by an obvious temperature shift 12 to 16 days before you bleed.

Ovulation in the previous cycle helps to confirm that your bleeding is true menstruation, not ovulatory spotting or abnormal bleeding unrelated to menses.

Note that this rule may not be reliable for women approaching menopause, because premenopausal hormone changes can result in dramatically early ovulation.

2. Dry Days

You’re highly unlikely to be fertile during your dry days.

Assume that you have a 28-day cycle. If you finish your period on day 5, and ovulate between day 12 and day 16, your dry days are likely to be from day 5 to day 10.

Of course, not everyone fits perfectly into this pattern.

Regardless, the most reliable way to identify your dry days is by paying close attention to your cervical fluid/vaginal discharge.

As the name suggests, your dry days are those days when you observe no cervical fluid or wetness at any point during the day. 

Note that semen can mask the presence of cervical fluid. But if you’re dry all day the day after intercourse, you’re safe to have unprotected sex again that evening.

For an enhanced sexual experience during your dry days, check out Passion Lubes, the best selling lubricant on Amazon. 

3. The 3rd Consecutive Day Your Temperature Remains High

If you track your body temperature, you may notice a rise in temperature 12-16 days before your menstruation by 0.4 to 1 degrees. The rise of temperature usually occurs immediately following your ovulation. Check out my basal temperature chart and how you can chart your own. 

If your temperature continues to remain high for 3 days or more, you’re considered safe to have unprotected sex after the 3rd day.

However, if your thermal shift is not obvious, or if your temperature falls below your baseline temperature after its peak, you should use a more conservative method.

Start tracking your body temperature, you'll learn a lot about your menstrual cycles. And it will be an eye opening experience! All you need is a digital basal themometer.

4. The 4th Day after Your Peak Day (Ovulation)

Once you see your vertical fluid changing from wet, clear and egg white-like to dry, you’ll know that your peak day (ovulation) has occurred.

And once you’ve seen 4 dry days after your peak day, you can assume you are no longer fertile.

Whether you want to get pregnant or avoid it, it's important to know when you're ovulating. And the easilest way to know is to take an ovulation test. 

Additional Notes:

1. When you notice a rise in body temperature and it remains higher for 3 days or more, you can assume that you have already ovulated.

2. For this reason, cervical fluid is the most reliable fertility sign to observe before ovulation, because it reflects higher estrogen levels, indicating the impending release of the egg.

3. After ovulation though, temperature is the most reliable fertility sign, because it confirms that ovulation has indeed occurred.

4. Take charge of your fertility with our free Period Calendar and Ovulation Tracker. It’s a great tool to track your body temperature, vaginal discharge, menstruation, ovulation, and more...

5. It may take a couple of months to get familiar with your menstruation/ovulation cycle and the signs to watch for. It’s well worth it though, considering the potential consequence – and the worry and fear of an unexpected pregnancy. 

6. Just in case you're wondering if you may be pregnant, don't worry. You can take an early pregnancy test. 

7. To learn more about your menstrual cycles and fertility, I highly recommend Toni Weschler's Taking Charge of Your Fertility, The Definitive Guide to Natural Birth Control, Pregnancy Achievement, and Reproductive Health. It's the best book I've read on this subject. 

Personally, I use the Fertility Awareness Method for birth control. I like its naturalness. I also find it a wonderful method to help me stay in tune with my body’s rhythms.

Hi, dear. If you menstrual cycle is regular and is 27 days, this means that you ovulation period - the fertile time, when you can get pregnant - is somewhere between the 12th day and the 15th day of your cycle. So, on the 20th of December you will be on your 22nd day of the cycle, which means that you're in the safe period. Hugs!

Dear Gen,
it is indeed possible for you to be pregnant, since the ovulation occurs between the 12th and 16th day of the cycle... Right on time on your case.
Good luck and lots of love.

Hi Teco, if you have a 28 day menstrual cycle, you're likely to ovulate on day 12-16, starting from the first day of your period. So if you had your period on Nov 21, you are likely to ovulate on Dec 3-7. Have you tried our free period tracker? It forecasts ovulation and period days for you in the next 12 months. Great for planning! Simple click on the sign up bottom at the top of the page and you'll get instant access :)

Women usually ovulate mid-cycle between day 12 and 16. So it's unlikely you'll get pregnant on day 5.

It's highly improbable for you to be pregnant since the ovulation normally occurs between the 12th & 16th day of your cycle.

Hi, Bernice! How long is usually your menstrual cycle? The ovulation moment occurs usually around the half of the cycle (days 14, 15, for a 28 days cycle or on days 12, 13, if the cycle is shorter than 28 days).
If you had your menstruation on 19th of September, this means that the 8th and 9th of October (when you had unprotected sex) were the 20th and 21st days of your cycle, which usually are not included in the fertile period of the middle of cycle. So I think there are more chances that you're not pregnant. Be well and take care!

Dear, Kelly, how long is you menstrual cycle? Are your periods regular? Usually, the days before menstruation are safe. So,in your case, the probability for pregnancy is pretty pretty low. Try to track your cycles and you will discover more about your body and the safe days for sex. :)Be well!

Hi Anna, it seems likely that you had sex on a "dry day". Moreover, the egg white discharge is an indicator of ovulation around the mid point of your period. It's true that sperm can live inside the body upto around 5 days, but as i say it seems unlikely that you are pregnant. The best thing to do if you're worried is to do a pregnancy test, and put your mind at rest.

Dear Francisca,
if you have an usual 29 days cycle, you shouldn't have been fertile the 20th day. However, if your cycle is sometimes irregular, it's hard to tell... What kind of irregularity is occurring? Is it like a day or two... more? If you haven't already, I invite you to subscribe to the free period tracker. It is a great tool to keep track of your cycle...

Hello Jing! I am new here and happy to be here.I need your thoughts about a concern that i have.
My husband and i are in a long distance rel and we havent had sex for almost a year now. He came home after 8mos he got home March 30th. We had sex without a condom the next day i got my period. I usually get it the first of the month. We did not have sex until the 6th of April after period with a condom and every night sometimes with a condom on some nights we did the pull out method. The last time we had sex was april 13th. I have been experiencing sore breasts since Sunday i get sore breasts before but not like the one i have now also today i noticed a creamy white discharge like lotio and loeer back pain. We have a 9 month old and not ready to have another baby.
I want to know if as early as now i could get the pregnancy symptoms or this is a case of pms. I am due to get my period 2 wks from now. I am getting so stressed and paranoid here. I need thoughts. Thank you so much

Bori, it's generally safe 4-5 days after you ovulate. The most accurate way to know is by tracking your basal body temperature, and the second best way is to observe your vaginal discharge (i.e. you're dry with no discharge). Hope this is helpful.

Looks like you had unprotected sex on day 20, 8 days before your period. This seems to be your safe days.

I track my temperature and try and determine the mucus. What is considered the norm as far as temp goes. After 3 high days is it safe to have sex on day 4. Also does the temperature stay high or drop down to base until my next menstrual cycle. Im trying to figure this all out. I found that the ovulation strips returned positive about 4 days prior to my first high temp reading so i am a little confused, i am 45 years of age.
