RH sensitization...

Has anyone else been told they have RH? I forgot all about my doctor telling me this only because we arent trying to get pregnant right now. It was like 8 months ago that he told me this but I was kind of zoned off because I had just been told I lost my baby. Just need some insight. I've googled but I want to get other doctors opinions because I've had two healthy pregnancies. My daughter turns 2 on December 1st and my son turned 3 on August 14th. I just don't understand.. I've had two miscarriages. 1 before I got pregnant with my son and another a few months ago (about 8 weeks ago). I was like 3 weeks pregnant...if that. Also super sorry if I post this in the wrong group area...I have no clue where to put this..
