The time you are most likely to get pregnant is about halfway after the last period in your menstrual cycle, when ovulation happens. Ovulation is when an egg is released from the ovaries. BUT following a safe period might just lead to an unwanted pregnancy. This because it’s very hard to predict exactly when the egg will be released, random changes occur – trust us! Also, females can be fertile for a couple of days before and after ovulation.
If you are having sex it’s best to find a reliable birth control method to prevent pregnancy, like the pill or an IUD. And always use condoms to help prevent STIs/STDs.
