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 sex with my boyfriend in the night then got an emergency pill in the morning but i dont know when my ovulation takes place…am i likely to be pregnant
My boyfriend and me have had unprotected sex for about 2 weeks, not every day but every other day so a total of 12 days, and I was in my fertile week last week while we had sex. Is there a chance I’m pregnant? Or going to get pregnant if I’m not showing signs yet?
All things being well, your chances of conceiving would be high if you have sex during your fertile week. If you conceived, you may not be experiencing pregnancy symptoms yet. Wait to see if you’ll miss a period and take a pregnancy test one week after that.

Ive been with my boyfriend 2 years, we had a little break July 2015 and I slept with another guy. Just once somewhere between July 10-25. Me and my boyfriend got back together August 2015 and I moved back in with him. I do recall having a period after I slept with the other guy but I’m not sure the dates..it could be from the end of July to the beginning of August. But on Oct 3 2015 I went to the er and they told me I was about 6 weeks pregnant. And I’m so scared the ultrasound may be off and this baby may not be my boyfriends. Nov 12th went to the obgyn and they said I was 11 weeks 5 days, but I heard they can be wrong can they be that much wrong or just like a week or 2? And does it take 2 weeks after you have unprotected sec to ” become pregnant “?
Don’t worry, the dates are too far off. Ultrasounds are pretty accurate. You’re just being paranoid. It’s your boyfriends! 😀
Hi. I had unprotected sex on 23rd November and the first day of my periods was on 11th November… Will I be pregnant?
You need to confirm the number of days in your cycle. If you have a 28 days cycle then your fertile period was from November 23 to 27, 2015. The chances of being pregnant would be high. If you have a different cycle then the response would relate to the amount of days in that cycle.

It is possible that you did not conceive. You were most fertile from November 27 to December 01, 2015 (for a 28 days cycle). The Plan B pill is a safe medication, do not be turned off by the side effects. You can still take it is you want to ease your mind a bit more.

I had my last period on October 14, and now I have 4 days missed my period. I did pregnancy test it showed negative. I had unprotected sex. Is there a chance I can be pregnant if I miss my period for four days only, and when is the best time to do another pregnancy test?
Your period may be delayed or missed for different reasons. 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.
doc…my last period is on last nov.14 2015 and nov.17 and 18 i have unproctected sex with my bf it is posible that im geeting pregnant.?
I had my period on November 5th and my cycle is 28th. I had unprotected sex on 18th. Please it’s possible that I am pregnant?
It is possible for you to conceive since you were fertile from November 17 to 21, 2015. Your next period is due on December 3, wait to see if it will come.
I had sex on Nov 4th, 2015, and he definitely did his business without protection. That was day 1 or day 2 of my ovulation week. I am due for a period on 11/23rd. Could I be pregnant? I feel really weird. My stomach has been turning and I am sick with a watery mouth since the last couple days. I just pray if it has to be something then it is a baby and not an STD. I prefer nothing! Do I have something to worry about?
The best way to determine if you are is to wait to see if your next period is late. If it is then take the test one week after you’ve missed your period. Don’t start worrying – it may delay your period even more.
