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.
Hopefully, you will now know what’s the chance of getting pregnant if you had unprotected sex.

Me and my girl had sex October 1st 2 days before her period and I used protection when I penetrated but when we first started I rubbed across her vagina b4 I strapped on the condom. Her period came on Oct 5 Bt it lasted regular 5 days. Now it’s the 29th and she says her period is due on the 31st but always be early but it hasn’t come yet and now she’s worried she could be pregnant. We haven’t had sex since the 1st. Help please can you get pregnant even if her period came on after sex? How high is the chance?
It is possible that she is not pregnant. It seems her period may be delayed for other reasons. It is possible to have a period and be pregnant but since you did not penetrate her, the chances of pregnancy would be low. If she does not have a period by November 7, take a pregnancy test for confirmation.
I lost my virginity October 17th. My bf went inside me twice without a condom to pop my cherry before he put one on. He did not ejaculate. Also on that same day I was 2 days before I was going to End my period. Any chance I am pregnant? I do have head aches and food cravings but I am very paranoid about this. Also my other question is if I had sex while I was on my period will I miss my next one if I’m pregnant? Lastly today is the day I’m ovulating… if it helps answer any of my questions.
Hi,It is unlikely that you are pregnant as he would have to ejaculate or pre ejaculate inside you for pregnancy to be possible.
I started my period on the 7 of October (which was on the 24 day) but it was all brown blood through out the day and only on day 8 it started feeling like menstruation (pains and thick blood) I had it for 5days (counting from the 7th) my cycle is not regular anymore I was on patch birth control which I stopped 3months ago. I had unprotected sex on the 23 which was day 18 of my period today it’s day 26 and no sign of my period. Am I pregnant? If so is there a chance I can terminate without op? I’m not ready yet I know I should have known better but mistakes do happen. Thank you in advance!
Hi, Take a pregnancy test to find out if you are pregnant then talk to a doctor about the options you have if you can take the abortion pill or operation .good luck!

I got my period on October 2 and had it for 6 days and had unprotected sex a couple times with my boyfriend then got my period again on the 27th of October for 3 days. Could I be pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. It is important to know the number of days in your menstrual cycle and whether you have regular or irregular periods. This information is needed to provide you with the most accurate response.
Also my cycle normally goes every 21 to 25 days and it lasts 3 to 5 days. I know I ovulate after my period for 7 to 9 days and my next period after my November 1s period (if I don’t miss it) should be November 26th
Hi ! I recently had unprotected sex with my boyfriend 4 days in a row, one week before my period that’s suppose to come. So we has sex October 23-27 and my period is suppose to come November 1st. He did not ejaculate inside of me , but he did mention precum, and wasn’t sure if he “precame” inside of me or not. I’m definitely concerned that I might have conceived or will conceive. So my question is , if i did conceive will I get my period on the 1st or will I miss it , and should I or should I not take a pregnancy test and when ? Thank you for any and all answers !
You should wait to see if your period will arrive on November 1. If it does not come then you need to take a pregnancy test 1 week after. You can get the most accurate result if you wait at least one week after missing your period. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time. The urine-based home pregnancy tests offer great accuracy.
Thanks for the advice ! Also I took a clear blue pregnancy test today and it came back negative. Is that accurate or is it to early to tell ?
Please doctor, i had sex with my boyfriend on the 29th of october and am expectting my period on the 2nd of november, is there a chance of been pregnant?

You ovulated from October 27 to 31 – outside of the days that you ovulated. It is possible that you did not get pregnant.
