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%.

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.

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 have Irregular periods, in September I had my periods from 28-01 October, then the next were in November 9-11th, which is a 42 days cycle, which can vary at times to less than that. So me and my boyfriend are planning on starting a family. My expected days of periods are on the 21 December 2015. We started having unprotected sex as from the 21 of November 2015, ovulation as per calculations was on the 7th December 2015, and the fertile days ranged from 2-8 December 2015. All along since 21 November 2015 we have been practicing unprotected sex, 2 days back I experienced tender Breasts, cravings, slight nausea, mood swings and lower abdominal pain. Today wen I woke up I had terrible cramps on my lower abdomen like I usually do when getting my periods, to go pee, I observed small blood clots on the tissue, then I decided to wear a pad, which later on is filled with blood and as I urinate. I’m very confused and stressed. Please do help me with an advice.
I had protected sex, but the condom broke unknowingly. My period came that morning, but could I still possibly get/be pregnant?
Hello, No you cannot be pregnant while you saw your period,however you can mistaken other bleeding for a period which in that case would mean its possible you are pregnant.
