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.

our last sex was on august 1 and it was the first day of my fertility according to my calendar and then I had my menstruation on aug 20. But now I’m already 10 days delayed. Is there a possibility that I’m pregnant?? I’m really worried. tnx
Hi Rine, Did you have unprotected sex after aug 20 when you saw your period? if you did you could be pregnant. if you become too worried talk to your doctor.
Help please!
I had sex with my partner on Tuesday the 8th September which he fully ejaculated and then slept with someone else on the 11th of September which he pulled out. My ovulation date according to those calendars is either the 9th or the 13th of September. I am now pregnant and not sure who the dad could be. How do I know? They say sperm can live in for up to 5 days so I’m thinking it’s more my partner. I also know that sperm can detect and kill off any foreign sperm having said that he didn’t fully ejaculate.
Thanks guys.
Hi Rosie, Precum can also get you pregnant so it would be hard to tell who the father is without a DNA. A DNA is the only way to be certain which one is the father.
My last period the first day was September 2nd. I had unprotected sex over two days ago. But I am having menstrual cramps. Could it still be possible that I am pregnant?
Hi Nikki, If you had unprotected sex then yes it’s very possible to be pregnant.
I had unprotected sex with my boyfriend 5 days before my period was due. 3 days after I started to feel nauseous, and sick to my stomach. The day before my period was due I experienced brownish spotting and some bad cramps and back pain. The day after my period was due I had light bleeding and cramps that stopped that night. Is there a chance that I may be pregnant?
Hi Kia, Yes it is possible to be pregnant, take a test or visit your doctor.
Hello my first day of my last period was September 16 of 2015 I have had sex on my fertile days and my ovulation day was September 30 could I be pregnant by having unprotected sex on those days thanks
Having sex on your fertile days will increase the chances of being pregnant. It is possible that you conceived.
Me and my fiancé did the deed on sept 29th unprotected. I had my period from sept 25-28. 29th with some spotting. My cycles are 23-24 days. My feritly friend estimates my fertile window to be oct 1-3 and my ovulation window oct 4-6. What are the chance of me becoming pregnant?
If you have sex before and during your fertile days, you have a great chance of being pregnant. You had sex just before you fertile window – it’s possible for you to conceive because an egg can survive for about 24 hours after it’s released from the ovary. If sperm are present in the fallopian tube at that time, one of them may fertilize the egg and lead to a pregnancy. Sperm can survive in the reproductive tract for up to five days; it’s possible that the sperm may still be hanging around during ovulation, ready to fertilize the egg.
Thank you very much
Hi, I had my menses on the 18th of August and I started having unprotected sex with my hubby since the 22nd of Sept, now my tummy feels tight at every slight in take of food, I feel nausea sometimes, I also puked slightly yesterday morning. Could this mean am pregnant?
The possibility of you being pregnant depends on whether you were fertile on the days that you had sex. It is important to know the number of days in your menstrual cycle in order to respond accurately. If you have a regular 28 days cycle then you would have been fertile from August 30 to September 03, 2015. If your cycle is irregular then the dates would be different. You need to confirm the number of days in your menstrual cycle.
Pls Help My Fertile Period Was On 26-28 Sep. I Had Sex Wth My Bf On 29 Sep. And I Took Emergency Pill On 30 September So Could I Be Pregnant Help.

Hi, my last period was on September 2, my fiancé and I had unprotected sex on that same day, the 22, 23, 25 and 26. I just got my period this morning September 30th is there any chance I could be pregnant? I have a 2 year old daughter who was conceived around this same time of the month about 3 years ago. I ended up getting my period 3 days after the unprotected sex but found out I was actually pregnant. Could this happen again?
Hello. Yes, it could happen again. Continue to monitor your body for other pregnancy symptoms.
I HAD UNPROTECTED SEX TWO DAYS BEFORE OVULATION…Now I’m a day late of my cycle.
Hi my periods started 25th of August 2015 ends on the 28th of August 2015 and I had sex on the 21st of September 2015 using a condom but unfortunately it slipped off. I would like to know if I might be pregnant or not.
If you were fertile on those days then the risk of being pregnant would be high. The best way to determine if you’re pregnant is to do a pregnancy test 1 week after you’ve missed a period.

Hi Mampho, It is possible if sperms from the condom got inside you but lots of things can delay a period too.
Am 36 years old I just got married, I have been trying to conceive for 3 month now. I don’t know what is causing the delay.
Hello. The best way to increase your chances of being pregnant is to track your menstrual cycle every month to determine your fertile days. If you do this and you have regular periods, then you can easily identify the best days to have sex. If you have a smart phone, you can download an ovulation app to guide you.

Pls I’m so confused I need to know the father of my child I had a protected sex on 26th of Aug. I later had an unprotected sex on 28th of Aug which the guy didn’t release on me then I saw my periods on 30th-2nd of Sept I then had another sex on 6th of Sept nd I went for a pregnancy test on 27th of Sept nd was confirmed 5wks pregnant pls wen did I conceive nd who could b d father of my child am so confused?
If you’re positive that you were protected when you had sex on August 26 then your partner then may not be the father. Having unprotected sex increases the chances of getting pregnant and although you believe that your partner on August 28 did not “release” on you, it is possible for sperms to be prematurely ejaculated before he climaxes. Based on the fact that you’re 5 weeks pregnant on September 27, it is possible that you conceived on September 6.
Hi. I’m so confused. I had unprotected sex a couple weeks back but after I did my period came, I was wondering if I could possibly be pregnant even though my period came after the unprotected sex? Help me please.
Hello. It is possible that you may not be pregnant. It is also possible for you to have a period during pregnancy.
