When you are having sex, pregnancy is always a real possibility. Sex, like other fun activities, comes with certain risks if you are not using protection, with STI’s and unwanted pregnancies being the most obvious ones.
If you want to know what’s the chance of getting pregnant if you had unprotected sex you have come to the right place.
Like others, you will hear many rumors about where and when you could get pregnant. For some women, the thought of getting pregnant is met with great joy and anticipation, while for others it’s a cause of worry.
This is why most women in the reproductive age or the ones who are trying desperately to conceive will have many questions or doubts about their chances of conceiving.
We will look further at this below to help you understand more about unprotected sex and pregnancy.
What’s the Chance of Getting Pregnant If You Had Unprotected Sex
There is a good chance that you could get pregnant nearly any time that you engage in sexual intercourse without using an effective birth control. This scenario is familiar to most women.
Pregnancy usually occurs around the ovulation period, the time when your ovary releases egg in the fallopian tube. If you are having regular periods, ovulation will take place midway between your menstrual periods.
Ovulation usually happens midway between the first-day of 2 consecutive periods, but this can vary from the eight day to the twentieth day of a 28-day cycle.
Researchers calculate the average risk at varying times in a monthly cycle of a woman, but you should know that your risk can be lower or higher.
You cannot know the definite time of your ovulation, which is why the researchers use the monthly cycle of a woman when calculating the average risk for pregnancy.
Figuring Out the Chances of Getting Pregnant If You Had Unprotected Sex
You are more likely to conceive if you have unprotected sex during the middle 2 weeks of your cycle. The time varies, but many women ovulate about day 14.
You will have the highest risk of pregnancy by having unprotected sex one or two days before your ovulation starts; when the ovary releases the egg.
This is a 30% chance. The risk of having unprotected sex and getting pregnant three days prior to ovulation is 15%. You will have a 12% chance on the ovulation day. [1]

In the real world, large studies show that women who engage in unprotected sex during mid-cycle have a much lower chance of getting pregnant as the risk is around 5.8%.
This is because you will have a much lower risk of getting pregnant if you engage in any sexual relations on the ovulation day and any day besides the three days prior to.
Not Getting Pregnant After Having Unprotected Sex for Months
There are times when having unprotected sex is not enough for you to get pregnant. You could be doing this for months with no luck.
Thankfully, there are certain things that you could do to increase your chances if it’s taking longer than expected for you to conceive.
This includes doing thinks like monitoring your ovulation, using an ovulation predictor kit, charting your basal body temperature, as well as checking and observing your cervical mucus.
When you have an idea of your ovulating time, you can start to time your sexual activities around that period. If you are using this method, you must ensure that you are having sex 2 days before your ovulation day or every other day during the week of your expected ovulation. This will boost your chances of conceiving.
If it’s a case where you have been engaging in unprotected sexual activities for more than six months without success, you could visit your doctor or ob/gyn to know about the alternative treatments that you could use for fertility problems. There are several solutions available and they are very effective.
How to Know When You Get Pregnant
The most common sign of pregnancy after unprotected sex is missed period. However, this missed or late period is not a sure sign as there are many other things that can cause it besides pregnancy.
This includes using birth control that contains hormones, stress, sickness, improper eating habits, or too much exercise.
It is pretty common for teens to have periods which come later than normal or missed periods because it could take several years for them to have a regular cycle.
So, the best way for you to know if you are pregnant is to do a pregnancy test. These are easy to get nowadays because they are available at drugstores or health centers.

My period came on July 5 and ends on July 11. We had unprotected sex in July 17. Is it possible to get pregnant even if my menstruation comes every month?
if you got your period after the 17th July then you are not pregnant. next time use protection so you wouldn’t be stressed out about whether you’re pregnant or not
My boyfriend and I didn’t have sex, it was basically only penetration on August 28th. That was two days before I had to get my period and I got it on time. Is there a risk of pregnancy considering two days before a period isn’t a fertile period?
I had a baby June 2, I got on the BC patch July 7, a tues. I removed and added a new one on time for the 3 weeks.. Except I didn’t take it off on time for the 4th week (the off week.. Supposed to get period) I ended up taking it off on sat. 1st of Aug. But my period started late Thursday July 30 into early morning fri july 31st i noticed light spotting and it started a normal to reg menstrual flow for me and lasted until July 5 where I no longer needed to wear anything anymore. Well I stopped taking it due to my significant other Being away for some time I felt I didn’t need to take it therefore I’m not going to be intimate. I found out he was arriving home sooner than I thought so I automatically put a patch on. That was thrus Aug 20. He came home the next day and of course we missed each other so…. We couldn’t seem to get enough of each other and that was late night on the 21st into the 22nd. I was supposes to get my period around the first of the month.. By now I’m sure…. That period I had was my first period since the birth of my baby and the healing process… Could I be pregnant or did I just completely like change my cycle by doing that? I’m just really worried and would like some advice.. I have a 5 yr old, 2 yr old and now a 3 month old….. I am not ready to have another baby! Please give me your advice so I can relax!
Hi Worried, I don’t think you have anything to worry about since you put the patch on 24 hours before he arrived. Maybe you are stressed and it’s delaying your period as a lot of things can delay your period.
Thanks for replying! I’m hoping that’s what is going on… I am totally stressed. I still haven’t gotten my period though.. For comfort I think within the next few days I’ll grab a pg test just to be sure and hopefully be able to release a little tension. I will make a comment when I do for results!
So I just got my period and on thrus I’m supposed to have my off week for the patch… Which means on the 17th i would start my next month of BC patches… And being the 20th is the 14 day ovulation period should I just use a back up method while intimate during those couple of days to be safe? What do you think?
Hello, I had unprotected sex a day before my ovulation, so I took levongestrol 0.75 after 6 hours.
I took the next pill 1.5 hours late, I was so worried so I took another 1.5 levongestrol after 12 hours and another 0.75 exactly 12 hours after that.
What should I do now?
Is there any chance of pregnancy?
Hi Lili, I don’t think so since you took another dosage,Because you can become pregnant soon after treatment with levonorgestrel, you should continue using your regular method of birth control or begin using regular birth control immediately.
So I had sex once on the 13 of June I then had my period come on the 29th which from what I remember was quiete normal, then sex after period regularly then end of July I didn’t get my period and found out I was pregnant. Today I am 10 weeks according to ultrasound when did I conceive? Is their any chance I could have conceived in June?
My girlfriend and i had unprotected sex last September 3 2015 and She had her 1st day of period last August 16 and it ended up last August 19.. could she become pregnant?? thank you
Hi! My last period was August 19-25th. We started last night (September 5th) having unprotected sex in hopes to have another baby. On my period log, it shows that was my last “fertile” day. I still get confused with how it all works, but I’m expected to have my next period the 16th. Is there a possibility I could be pregnant or will I start my period in 10 days?
I had sex with my gf on 7th of august (last month) two days after her periods were over. Although she has irregular cycles but it is 6th of September (the next month) and she has not gotten her periods. I used protection but instead of one i used two simultaneously one over the other. What are the chances of her getting pregnant?
if the condoms didn’t break than you should be safe. however, never use two condoms at once! the friction between them leads to a higher chance of condom breakage
