Hi, I have had the copper t IUD for 3 1/2 yrs. I have had a period, regularly every month except this past July. (It lasted the almost the whole month)It is now September 26, in late July, early August while having intercourse with my husband he hit my IUD and it hurt bad. 2 weeks after something poked him. About a week ago it poked him again. I am contacting you because I am a week late and feel pregnant. I have had three pregnancies before, but the symptoms could be chalked off as PMS, or the fact that I am stressed and wishful thinking for another. I have taken 4 at home test and 2 were invalid and 2 were negative. I have an appointment with my Dr but not for another 2 weeks, please help.
