Ok so on 9/13/07 i have an IUD removed because it was causing problems for me. I had unprotected sex with my fiance that night. My last period was 8/28/07. Friday I started bleeding heavily.....went through a whole box of tampons in 2 days....I bled like that until Friday the 21st. We have had unprotected sex plenty since then. After the 21rst to now I have been having cramps being very nauseous, headaches, not being able to eat certain things without gaging, and feeling achy in my lower abdomum. I took a HPT on the 28th and again 2 days on the 1rst.....both are negative. I was told that the heavy bleeding was from the procedure of removing the IUD....I haven't had a period since 8/28. My symptoms havent changed.......Should I be worried? what is wrong with me...
