I just got a new insurance and it's not active until february 1st, would really appreciate any advice as I'm worried. I'm currently taking birth control (been taking it for 8 months). My last period on the pill ended January 5th. After that i didn't have my period until the 16th. On the 16th at 6am i noticed i was bleeding, yet the blood was a dark color seemed black. The bleeding has continued and the color has not changed. It's a bit lighter, more like a brown and more fluid like. Throughout all this I've been having cramps but nothing bad. Recently i started to have really bad sharp pain that comes and goes on the right side of my abdomen. The sharp pain comes and goes for hours, until eventually it stops (~4 hours). I continue to take the pill (marlissa), and will be do for my actual period next tuesday. If it does not stop that would mean 22 continues days of bleeding (brown blood). Took a pregnancy test this week, which came out negative. What can this be? and what can i do?

Hm it's hard to say.  The colors of black and brown blood mean its old blood.  Not fresh.  Hormonal imbalance can be the cause and this is not dangerous or something to be scared about.  I'd use back up birth control right now (condoms) and when your insurance is kicked in, see your doctor.  Doubt you are pregnant and more just experiencing maybe too much progesterone in your system.  February 1st will be here in a few days, set up an appointment and talk to a doctor about it.  Your pill may need to be adjusted.  good luck
