So, all my levels were close to zero 03/27, because I took a test and it was negative. I tested + on OPK 03/31 (no wasn't left over pregnancy hormones). I took a test 04/10. Faint positive. Still faint today, but I started bleeding a little pink here and there. Now I'm scared. .I wonder why my faint test aren't getting any darker. I never got my period after my miscarriage 03/08.
