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.

My bf and I had unprotected sex a day after my period ended there were still blood spots when we finished having sex. What are the chances of getting pregnant?
It is possible but it depends on the number of days in your cycle. Women with a short cycle, for example 21 days, who bleed for 7 days, can ovulate right after their period.

Hi. Ti incease your chances, you need to track your period and determine your most fertile period for each month. It is important for you to keep a record of your menstrual cycle on a calendar or on a smart phone; there are many ovulation apps available. Track your start date every month for several months – this will help you to determine the constancy of your periods and your fertile period.
Ok, so my lmp was Sept 19th- 25th which was kinda long for me, my usual period is 3-4 days. Anyways, I’m ovulating Today (I think), cervix is softened, high, cm is clearish but not quite like raw egg whites yet. My man and I are ttc so we had sex Sept 26, 29, 30, also Oct 1, 2, 3, & 4… We will continue to try till the 7th(fertile days are supposed to be 1-7). When can I take a hpt? What are our odds of becoming pregnant since we are sexually active throughout my entire fertile window?
Hi Serria, Its possible that you are pregnant take a HPT in a week or two good luck!
Last period was Sept 16-20 & I had Unprotected sex on my ovulation & Fertile days & Then October i went to use the bathroom i wipe myself and it was Pinkish Red It only last for a hour and my period is due on Oct 14 Can i Be pregnant?
Hi . Me & my boyfriend are trying to have a baby. My last period started September 19th & ended on September 23rd. My fertile days are October 1st-7th. I ovulate October 6th. Me & my boyfriend had sex today , October 4th ( 2 days before ovulation ) can I get pregnant?
Hello. Yes, you can but have sex as often as you can during this time ton increase your chances.
Hi, my last period was September 11, 2015. Me and my boyfriend had in protected sex on September 26, 2015, October 2-4 2015. My period is supposed to be here on the 9th.
What are the chances of me being pregnant???
P.S. We are trying to conceive(:
Hello. You were most fertile from September 23 to 27, 2015. So is is possible that you conceived.
Would you know the percentage?
Hey. I got my period start on 17 Sept till 21st Sep. Me and my boyfriend had unsafe sex on Oct 1. Now do I need to take pills or is it safe?
It would be too late to take the morning after pill. You would need to confirm the number of days in your menstrual cycle in order to determine whether you had sex during a safe window.
Hello,
I had sex with my other half on Monday 28th sept and was due on my period Friday 2nd oct. I’m very regular, like clockwork in fact but I’ve had nothing but a little bit of brown/pink spotting when I wipe. Nothing ever really on the liner. We didn’t use any contraception as we are trying and I came off the pill approx three months ago and my periods have been as regular as before. No idea when I was or am ovulating. Could I be pregnant?
Hi Annie, Yes it is possible that you are pregnant but its too soon to tell wait a week or 2 then take a home pregnancy test.
Hi my last period was from September 11 till the 14th, me and my husband just had sex last night. I know my period is about to come aging on the 11th. Could I become pregnant?
You were most fertile from September 25 to 29, 2015. So it is possible that you did not conceive then.
I and my gf had unprotected sex a day after her menses which was the 5th day of her cycle, and she took an emergency contraceptive pill Rogotinor like 30mins later!!! can she still be pregnant?
Once this morning after pill is taken within 72 hours as prescribed then it is possible that you’re not pregnant.
Hi this is my first time being here but anyways I had sex last Saturday and Sunday (Sept.26-27) and my boyfriend ejaculated himself in me both times and it (my period tracker) said on the 27th I was on my fertile window and since then I’ve had mild cramping, breast soreness, slight headaches and nausea. Is it possible that I could be pregnant? I also don’t know if it is too early to test its only been 8-9 days ….can it be a good time to do a blood test?
Hi. 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. This accuracy will depend on several factors such as how early the test is taken, if the instructions were followed closely, when ovulation occurred in the cycle as well as how early implantation takes place, and the sensitivity of the test.
It is always best to take a pregnancy test after a late period to avoid false positive or false negative results. If you have irregular cycles or you are not charting your cycles, it might best to take the test after passing the longest menstrual cycle.
Hi! My last period started on the 29th of August. Did the deed with my hubby, on the 17th of september without protection. Yet to see my period, could I be pregnant?
Hello. When was your period due? If it is at least one week late, then you can now take a pregnancy test for confirmation.
Hi, I had unprotected sex with my husband on the day my period ended and the day after, I have been having cramping since that week, had severe leg ache the first week along with breast tenderness, cramps and nausea. It has been about three weeks since I visited the doctor (who mentioned that I could be pregnant, but I’d need to wait until the 10th for an early pregnancy test), currently, I am having short nausea every time I eat something, my cramps are still present, my stomach is bloated but there’s no gas and I am passing a lot of milky white discharge. My breast still has the occasional prickly pain along with slight tenderness. I am confused. Could I be pregnant? I don’t have a Urinary Tract Infection so I am trying to figure out whether it is possible for me to conceive. Also, I have been suffering from very bad mood swings, and I can’t help it.
Hi Zuka , It does sound like your experiencing pregnancy symptoms it seems you could actually be pregnant, it is possible.
I experience a lot of acidity since the past week. Especially at night, is this a symptom?
my partner has menstrual on 13th aug till 15th aug. we had safe intercourse using condoms on 13th sep 2015 only… never between this period. but till point of the time she is missing periods. usually she takes 30 to 35 days to her next cycle. is there any chance of pregnancy?? kindly suggest us
Hi Kd, If you had protected sex and the condom didnt break then she is not pregnant. If you had unprotected sex any at all then there is a possibility that she is pregnant.

Hi Book Love, sounds like you were having irregular periods. Once you have had unprotected sex it is possible to become pregnant.

At times my period is irregular but never this long. yesterday I took a home pregnancy test and it was Negative-..Is there a possibility I could be pregnant?
Hi Crizty, Once you have unprotected sex it is possible to become pregnant the pull out method is not 100 percent effective since precum carry sperms enough to get you pregnant. I suggest you visit your doctor to find out
