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.
It is important to note that the home pregnancy tests are ninety-nine percent accurate if taken after you miss a period.

Hello, my last period was on Jan. 31,.and ended Feb.2 I had unprotected sex on the 3,6,12,13,14. I use the app called ovia, and it said my fertile days started around the 15 of this month. I had unprotected sex 6-7 times during Valentine’s weekend.. If I was fertile starting on the 15, what are the chances that I’m pregnant? It’s too early to rest, but need advice.
Anytime you have unprotected sex, you can get pregnant. I wouldn’t get stressed out, but please be prepared to recieve a positive on the test. It is not guaranteed, but just to be safe.
I had sex 2days before my ovulation and on the ovulation day what chances do I have on getting pregnant and how early can I know that am pregnant??
On the day of ovulation, you are at the highest risk for pregnancy. You will be able to take a pregnancy test 7 days after your missed period.
I been having unprotected sex for more than 6 months and I haven’t got pregnant. But can is there a chance I can get pregnant even if he doesn’t cum inside me??
There is a chance, but it is extremely small.

This month I didn’t have it yet and it’s already a week late.
Am I pregnant? is it possible? I know I had so much stress last couple weeks and lack of sleep.
No you are not pregnant. Your period is delayed due to stress and lack of sleep. Try to relax, and sleep more 🙂
Hi if I had sex 2 days before I ovulated then didn’t have sex during my ovulation. do I have any chance of being pregnant.

hey,my last period was on 11th of jan and I had sex on 9th feb. Is the risk of getting pregnant high?.i’m thinking of taking a pregnancy test and if the result is positive,can I take a contraceptive now and get over with it?.please help.
If you had sex on the 9th of february, you can take a contraceptive pill up to 72 hours after having unprotected sex. You just have to wait it out, and see if your period comes on time. I wish you the best.

Hi ,
In december i had my period on the 10th so i expected my period to come around thw same time in janurary but it didnt. I waited for it to come but when it passed 12 days my bf and i were eager to have sex. We had sex but he figured since theres a possibility i could be preggo he just ejaculated in me. Three days later my period came (14 days late). Now it is feb 13 and i feel very hungry , slightly tired and crampy with a dull thumping on my right side(abdomen)
Since it was unprotected, you could be pregnant. I recommend tracking your cycles, and taking a test if you miss the next month. Good luck!
