What is the risk of pregnancy if no protection taken before 1 day monthly cycle?

There is still a low, but existent, chance of getting pregnant if unprotected sex happens during any day of your monthly cycle.

The menstrual cycle is the monthly cycle of changes in a woman's reproductive system that makes pregnancy possible. It begins with the first day of menstruation and ends with the day before the next period begins.

Ovulation, which is the release of an egg from the ovary, typically occurs 14 days before the start of the next period. If sperm is present in the fallopian tubes at the time of ovulation, fertilization can occur and pregnancy can result.

Even though ovulation typically occurs 14 days before the start of the next period, it can sometimes occur earlier or later in the cycle. This is why there is a small chance of pregnancy if you have unprotected sex on any day of your cycle, even if it's not the day you expect to ovulate.

The risk of pregnancy increases the closer you get to ovulation, but it is still possible to get pregnant if you have unprotected sex on any day of your cycle.

If you are not trying to get pregnant, it is important to use protection every time you have sex. There are many different methods of contraception available, so you can choose one that is right for you.
