I m 17, I have not had sex for six months, after sex I took the morning after pill and I ve done a number of pregnancy test all negaitive, I had sharp pain in my lower stomach , and recently I ve got a sore nipple , I feel dizzy a lot, more than I should I d say pretty much everyday, I am over weight, but sick of my doctors blaming all my problems on that, is there any reason why I m in pain and dizzy all the time?
