So I found out that I was rh- with my son, during my 8 week check up I had the Mirena put in that was over 3 years ago, on December 2 I had it removed and then had a period on the 4th-6th, I have not had a period since. I have taken over 8 pregnancy test to all come out negative. Has anyone had complications receiving positive test results, could it even be related to the blood type??
