If a person is on the pill and they get their period is there any chance that they could still be pregnant? Can the pill force a period even if some one is pregnant? To me this seems like it should be an obvious no but i am not sure. Please help!
Thanks in advance!

User avatar Hello Kate121,

Anytime there is intercourse there is a chance of pregnancy but I don’t think that’s what you meant :wink: . If you’re on a “mini” pill rather than the full dose pill the chance of pregnancy are much greater, especially if you missed a pill, even by 6 hours. The full strength pill uses hormones to make your body think it’s pregnant so it doesn’t ovulate and than at the end of your cycle you take the false or filler pills and your body thinks it’s not pregnant so it sheds the uterine lining it thought it had a baby in and will start all over. The most crucial time to take your pill is before and after your period, this is the time when your body really wants to ovulate. The hormone levels have dropped to their lowest and your body feels the need to produce an egg for fertilization. The mini pill causes your cervix to produce thicker mucous so it’s harder for the sperm to get through it but doesn’t fool your body into thinking its pregnant and stop ovulation. If you’re late, even a few hours, you can mess the thickness of the mucous up and allow the sperm through. Sperms can live from 3-5 days inside the vagina so all they need is a chance.

A person may still have a period even if they are pregnant and on the pill, you don’t want to purposely take the pill to try and miscarry but if you accidentally take it because you don’t know, your body will try to protect the baby and your flow may be lighter. This happens all the time to woman on birth control pills. If you think your pregnant, contact your Physician right away for a check-up to make sure everything is starting out on the right foot.
