I had unprotected sex in August. I've been getting my period ever since then. Regular schedule, it's on time and it last the usual 6-7 days. I haven't had any symptoms of pregnancy. But I read online that you can have your period for months and not know that you are pregnant. Do you think I have anything to worry about? I've had a loss of appetite and constipation for the past week. I think it's because of stress but I don't know. I've pooped, but when they come out they are little and I've taken 3 stool softners and 2 mild laxatives, but nothing changed.
