if you are talking about the IUD...the 10 year one....with no hormones? i had that for years and here is my story. we decided we wanted to have a baby, i had my IUD removed around the 15th of November 2007, had a period on November 27 and got my positive test on December 19, 2007. So there you have it!! :) i am 35 weeks exactly today. ( not that it matters, but i have very short cycles...about 21-23 days) ↑
