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

Thankfully, there are certain things that you could do to increase your chances if it’s taking longer than expected for you to conceive.

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

I’m not sure if this is a reply to my question but I had my period (bleeding from 13-19th so I am not really sure if I was exactly fertile during that time. I had sex on the 22nd and the 22nd only and that’s when he finished inside of me. I also just started my birth control pills for the first time directly after. I know it takes time to go into effect. But I did schedule a doctor’s appt for June 3rd hoping to get answers. Do you think I should be okay?

I am very much worried. Can I get pregnant? We actually did not have any sex. Please reply as soon as possible. We had sex on May 16-17.

It is possible that you conceived since you had sex while you were fertile. Wait to see if you’ll miss your next period and take a pregnancy test at least one week after that date.
Hi I had unprotected sex day 25 of my cycle and was fertile. My period didn’t come yesterday and I was not trying to be pregnant. I am very, very worried. What should I do?
If you had sex during your fertile days then the chances of being pregnant would be high. You will need to take a pregnancy test by May 27 to confirm if you actually conceived.
I had sex on May the 14th which is 4 days before my period is due. I’m supposed to have my monthly visit on May 18th. I took a pregnancy test yesterday May 18th and it came back negative. And today marks the 31st day of my cycle which it varies from 29 – 31 days. Do you think I’m pregnant?
The chances of you being pregnant would be low because you were not ovulating at that time. You are also testing too early. Take the test on May 27 to be sure.
I had my period April 24th, 2016. My periods are always normal and come on time. It says my ovulating days were May 5th- 13th. I had unprotected sex and he ejaculated inside of me May 7th. Two days later I had pink spotting and on the 3rd day I had slight cramping in my stomach. I find it weird being I don’t even get cramps with my period. Now I’m really stressed I took 3 tests they are negative I got blood work done and it also came out negative. My period is due in a week I just find it all strange I was also so tired all of a sudden and been having serious chills. No morning sickness but I have been sensitive to smells. Unfortunately, I work at a hospital so Lord knows what we smell there. I’ve been pregnant before and I remember how tender my boobs were and this time they are not. I still believe I am pregnant I don’t know if I’m driving myself crazy or what!
It’s best to wait until you’ve actually missed a period to get the most accurate results from a pregnancy test. Wait to see if your period will come and then take it from ther.
