My doctor is going to put a Mirena IUD in and he decided to do a pregnancy test just to make sure. It came up positive and my count is at 1500. He says I am pregnant so he cannot put the IUD in. I am 36 years old and was told I could not get pregnant without help which I have had none and got pregnant for the first time at 35. What is up with my body and could this really be happening just 8 weeks later?
