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.

I had my period on Nov 3, 2015, had unprotected sex Nov 9, 2015 and Nov 14, 2015. I had period again on December 2, 2015 – had unprotected sex December 25 & 26 – had my period on December 31 to Jan 5, 2016. No sexual intercourse happened since December 31, 2016 up to this day. Today is January 31, 2016. Is there a chance that I’m pregnant?
It seems you’re not pregnant – you had 2 periods in the month of December and you have not had sex since your last period. Your period is delayed but this may be due to other reasons besides pregnancy.
Is it because im stressing out thinking that I am pregnant?
I was given a conception day of the 23rd. LMP was the 9th. Had a ONS the 4th (around the time I was expecting my next period) so far with u/s no change in date has been made but I worry that it’s the ONS and not the actual conception date. Is this reliable?
Hello, It would be hard to give you the exact time of when you conceived the doctors can only give you the closet possible date based on your last missed period so i would say it’s reliable.
I had unprotected sex on the 27th of December and again 10th of January..I haven’t seen my period since then I haven’t seen my period
My period started January 10,2016 I ovulated January 24 I had unprotected sex that same night could I’ve gotten pregnant?

My boyfriend and I had sex without using a condom a day after my period. .only to find out he already impregnated somebody on December. ..are there any chances of me getting pregnant?
Hi, since you had unprotected sex its possible you could be pregnant the only thing you can do now is take a pregnancy test to find out.
We had unprotected sex on 18th Jan 2016, her period 1st day was on 1st Jan and lasted for 5 days. I didn’t ejaculate inside her; she doesn’t have any signs of pregnancy, but she said she is feeling bit tired and having headaches. I believe this is just because of her office work and pressure. We’re afraid…is she going to conceive or not? And last month’s date actual date was the 25th but it was delayed and she got it on the 1st of January. The month before she had it on the exact time. Can we think she ovulates on the 14th? Each website shows each answer. We are confused and afraid.
Your girlfriend may not be pregnant. The stress of work can actually cause a delay in her period. As it relates to ovulation, the days that she ovulates depend on the length of her menstrual cycle. Typically, the menstrual cycle will last for 28 days, which is calculated from day one of a menstrual period to day one of the next cycle. Ovulation typically occurs 14 days before the start of your menstrual period. If your cycle lasts for 28 days, you can ovulate on the 14th day like the average female. However, you will start ovulating around the 11th day if you have periods 25 days apart.
