Okay so I'm SUPER confused and don't know what else to do. Every month since I've had my breast augmentation I have had faint spells when my period comes. Sometimes it's the first day- other times it's the 2nd days- but I get real hot and dizzy feeling and throw up and have to lay down on the bathroom floor to start feeling okay. I called the doctor who did my surgery and he said it wouldn't have anything to do with my period. June I didn't have a faint spell so I thought my body had corrected itself, and again in July I didn't have the faint spell. Well come August I was suppose to start my period on the 14th I cramped really bad that morning and prepared myself for full blown cycle, but it never came- it didn't start under Monday the 17th and come Tuesday I had my faint spell again and my husband rushed me to the hospital- I had a CT scan, ultra sound, tons of blood work and everything come back normal?!? Tuesday I didn't bleed all day, Wednesday I spotted Thursday I didn't bleed at all and now it's Friday and still nothing. OBGYN can't tell me what's wrong either- she seems to think I need birth control, but I don't want birth control b cuz I have been trying to get pregnant now for 2yrs2months. Can someone please at least try to enlighten me on what could possibly be going on? I'm 28 and have never experience anything like this- so any insight would be great! Thanks!
