I have always had messed up periods. I have been to my family doctor about them and to a OBGYN who takes females under 18. But me and my mom didn't like her. I get my periods about every 3 to 6 months. When I do get them they are very heavy and they hurt. This last one that I just got off yesterday lasted about a week and a half but it was off and on a lot. Then other thing is that it was so light that I didn't have to wear anything. But it was very dark brown, sometimes it was light brown. I got headaches for the last three days and I'm still getting them. Is there any chance I might be pregnant? If not is there a problem?
