Hi there was another thread thats probably 30 pages long regarding this topic. I got my IUD out June 5th of 2009 and I got a positive pregnancy test a month later July 4th. Like Ems said each womans body is different and mine just went back to normal. I had my IUD for 3.5 years and my periods didnt exist the last two years of the IUD. Good Luck!
I had my IUD (Mirena) inserted on June 13, 2007 after I had my son and had it removed on July 2, 2009, it took me 43 days before I got my first period, and I know some women who it's taken 90+ days to receive their first period. Your body's just trying to get back to normal, I know how frustrating it can be while your sitting in lingo, not sure weather your pregnant or when your first period will show up, but try to be patient it will happen when the time is right! Also your body will play tricks on you after the removal that make you think that your pregnant, I myself went through these, and boy are they not fun, especially since period and pregnancy symptoms are so similar. Also I know a very few women who have gotten pregnant right away after removal, so anything is posible, but most Dr's will advise you to wait at least one cycle so that your uterus linning is thick to hold the baby. It took me almost 7 months till I finally got my BFP (Big Fat Positive). I am currently 25 weeks 4 days with a healthy baby boy. Good luck and hope this helps!
