Okay so i had just given birth to my son almost 7 months ago, i had gotten my period for maybe the first 3-4 months after birth and now to this day 04-05-13 i havent had my period since the end of January. i am on birth control and i thought maybe that was what was making me bleed so heavly and it wouldnt stop so i quit taking it and the bleeding stopped. My doctor told me to start it up again and see if it starts my period but nothing yet. Ive taken about 6 pregnancy test and their all negative.. I did something i shouldnt have and started reading online about it and alot of it related to thyroid problems... Has anyone else had this same problem?!
