I started birth control pills a few weeks ago on the day that I started my period. After my period ended, everything was okay for about a week and then I started bleeding again.(light at first and now heavy). I've been bleeding for about a week now and today I started feeling pain in my lower abdomen. The pain is severe whenever I try to sit up, stand up, lay down, cough, breath, and move. Whenever I put just a little pressure on my lower abdomen it hurts. Can anyone please tell me what might be going on? I've also been extremely tired lately, more than usual, and I've even started to fall asleep while standing up or pacing around my living room, trying to keep myself awake.
