I have 3 periods in a month tell me am I pregnant

You can't get pregnant if you are having your period. It is possible to have bleeding while you're pregnant, in which case I'd suggest seriously you seek professional help, but if it is your period then it is impossible for you to be pregnant. If your period is abnormally spaced or if you're 16-18 or younger, I'd wait to see if they go back to normal, but if this keeps happening and it isn't normal, then you may want to talk to a doctor. It could be nothing, it could be something...
