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.

Hi I am in urgent need of advice. I last had unprotected sex with my boyfriend on the 26th of July, and I had my last period between the second and third week of July (which happened after taking a morning after pill). It was only a quick session and he swore to me that he didn’t ejaculate (and also since usually it takes him a long time). Can you get pregnant with precum? I was expecting my period to come by now but I haven’t had my period yet. Ive been sensitive and emotional lately and not sure if its Pms and that my period is late or if its just coincidence. I’m really paranoid and Im not sure if Its too late to take a pill. Please help. Thank you.
Hello Kara, It would be too late to take a pill,however getting pregnant by precum is possible but rare you maybe experiencing PMS and you worrying is not helping the situation try to relax.
Hi, my last period was on 27th and i had unprotected sex on 6th could i be pregnant? Stellah
I am kind of freaking out. So I started my period on Aug. 6 and it ended on the 11th. I had unprotected sex the day after it ended. He pulled out but I’m still worried I could be pregnant. I’m not supposed to get my next period until September.
Hi Kim, It is unlikely that you will get pregnant unless he did ejaculate enough sperm inside you to get you pregnant. if you have doubts that you may be pregnant check with your doctor in the meantime i dont think you should worry.
please respond urgently

Okay so I had sex most of the time of my fertile week I know it’s challenging to figure out the exact day of ovulation so I was wondering what my chances of getting pregnant would be?
If I missed my period on the June 10 and I had sex throughout the two weeks unprotected with my boyfriend, We had a disagreement and I had sex with someone July 4 . is there any way for me to tell who the father is .
Hello Bailey, It is possible you could have been pregnant before july 4th when you had sex with that other person there’s no way to tell for sure.
my last period started on July 25 lasted for 5 days and my period tracker says I was fertile from August3-August9 we had sex the 6th 7th 8th 9th some of those days more than once. is there a chance that I could be pregnant? *I hope so* just need opinions. I know that I had to be fertile on those days because I could feel pain in my ovaries which I normally feel each month.
Hello,
Im freaking out, I had unprotected sex with my husband Aug 6th and ovulated the next day. (I know I ovulated by cramp on side and egg-white consistency cm) a few days after I’ve been bloated, crampy, and tender breasts. Could I be pregnant? I’m going crazy, I can’t stop thinking of I can be or not so I don’t even know if my symptoms are real or not. Please help.
Thanks in advance.
My GF nd I had sex, after 20 days she had her periods which was late and now she has symptoms of pregnancy, could she be pregnant ?
Hello Nish, Let your GF take a pregnancy test that’s the only way to know for sure.
Plz help me out urgent…i hd unprotected sex with my gf and she was not in her periods…i hd sex on 11th and her period starts from 2oth….is there changes of getting pregnant….im very woried…plz
Hi Sn Sam, If her period came after you had sex why are you worried?? is she complaining about being pregnant?? i dont think she is pregnant but if you are unsure let her take a pregnancy test.
My period was July 30-august 5..
I think.. dried blood the last day.
On the 6th we had an accident.
My period tracker says I ovulate on the 15th which would mean I’m in the clear ..but I’m still a little unsure.
Last was a 29 day cycle. Next period was roughly 7 days… the one that just passed.
Am I really in the clear…??
Hi Shawna, If you are unsure take a pregnancy test to be sure.
I think it’s too early to test .
I’m due for my p on the 29th. /august.
But From what I’ve read. I think it’s not likely the day after your period. I just got worried. Thanks for responding. 🙂
I am in need of an urgent respond to my question. The first time I had sex with my girlfriend was July 16th ,2015. Last week she told me that she hasn’t seen her period so went for a pregnancy test at the lab which was carried out through her blood and the result we got was NEGATIVE. She complained again this week that she hasn’t see her period so I asked her to go for another pregnancy test through scan today and she came back to tell me that she is 7weeks and 6 days pregnant so I did my calculation and I noticed that between June 16,2015 till July 30,2015 that I had the last sex with her is not up to the weeks the scan result gave therefore I wanna know could this pregnancy be for me? I am confused
Hello Martins, when was your girlfriends last period? normally doctors calculate from the last period to the present time so that could explain why its 7 weeks
Well, I don’t know when she had her last period because we haven’t met when she did her last period. My question now is that from July 16,2015 that I first had sex with her for the very first time until when she went for the ultrasound scan on 10th of July, 2015 is not up to the 7weeks and 6days the result showed. I told her that am not ready for the pregnancy so she need to do abortion so she went to see doctor today(12-08-2015) And the doctor did another ultrasound scan for her and when the result came out, it showed that she is 5weeks and 5days pregnant so I became completely confused when she informed me via text message. How come the ultrasound scan gave two different result in a space of three days? I am begin to doubt it thinking she wanna trick me with the pregnancy, please advise
The ultra sound and the dr prediction (he is going by her last period not the day you conceived) is normally a few weeks off. my friend who is do very soon says the dr said she is due in 7 weeks going by her last period but the ultrasound says she is due in 4. its very confusing and she is probably telling the truth. all you can do is if you keep the baby get a DNA test. babies are Gods blessings but totally understand if you go the other way. Hope this helps. Prayers your way.
My last period was on July 27 I have a regular 28day cycle and I’m currently in my fertility (8th-12th) window I had sex with my boyfriend on the eighth and the ninth and today is my ovulation day and we’ve had sex twice. We are ttc by the way ☺️ What are the chances I am pregnant?
Hello Tommie, The chances of you being pregnant is very high since you had unprotected sex around the right time, all you have to do now is wait and take a test good luck!! 🙂
I had unprotected sex with my boyfriend yesterday I had my period August 2 , 2015 . & I suppose to ovulate August 17th , 2015 can the sperm stay alive until the day I ovulate ? I really don’t know I’m confused & I really want to get pregnant .
Hi Ciara, sperms can live up to 7 days i would suggest you have unprotected sex a day or 2 before you ovulate good luck!
i’ve had unprotected sex with my bf 4 days after my menses which last for 5 days and my cycle is 29 days. am i likely to be pregnant?
I calculated that i was ovulating on aug 2 so me and bf had sex the day before and on my ouvlation day now today i have had stomach cramps and vomitting. Could i be pregnant
Hi Kiesha, have you taken a pregnancy test yet, you could be pregnant.
Best to take a test on the day of your missed period! Morning sickness usually doesn’t start until 6 weeks! Good luck.
