If i got pregnant i wont get my periods?

No you won't get your period when your pregnant, but seeing as your asking this question take my advice and DONT get pregnant until your about 10 years older than now.

You get your period every month if your cycle is regular. Its your bodies way of telling you that you CAN get pregnant and that you've reached sexual maturity. Once you get pregnant your body doesnt go through its monthy changes because your body isnt releasing eggs. Once you have a baby it changes your body and if breast feeding you wont get a period for a few months but you CAN get pregnant when breast feeding if your not careful. The human body is a very clever machine.
