Do you still have a period while on birth control pills?

“Not really,” says Dr. Boyle. “It’s important to understand that the bleeding that you have while taking combined birth control pills is not a real menstrual period. “You have not had the increase and decrease in estrogen and progesterone, the endometrial lining has not grown and then shed, and you have not ovulated as you would in a true menstrual cycle. The bleeding you have is what we call a withdrawal bleed. You pause the active pills of the birth control pack, and this drop in hormones causes the lining of the uterus to bleed and shed.”

Does birth control stop ovulation right away?

This all depends on the type of birth control and where you are in your cycle when you start taking it. For example, with combined birth control pills, you’ll be protected from pregnancy right away if you start taking it on the first day of your period. Otherwise, you’ll need to use backup protection for seven days. For the mini pill, you’ll be protected immediately if you start taking it within five days of the start of your period. Otherwise, you’ll need to use backup protection for two days. You should always check with your doctor how quickly the type of birth control you’re taking becomes effective.

Can birth control stop suppressing ovulation?

It’s possible for any kind of birth control method to fail, even when you are using it perfectly. However, perfect-use failure rates for hormonal contraception are low. For example, the combined pill’s perfect-use failure rate is just 0.3%, meaning fewer than 1 in every 100 people would get pregnant anyway after a year of use. Due to human error, the typical-use failure rate for hormonal contraceptives can be slightly higher. For example, the combined pill’s typical-use failure rate is 7%. This is because you might forget to take it or take it at the wrong time.
