I just started a birth control that I used to take, which very well may be the cause of this. I got my period two days ago, and it started as brown discharge and then switched to thicker slightly clotted but more just stretchy thick blood. The weird part is I haven't used a tampon or a pad for the last two days because it doesn't come out except when I push it out. Ive never had anything like this, but I work heinous hours and have trouble taking time off. Should I be worried enough to see a doctor or is this normal?
