Is anyone rh negative and been having trouble conceiving or had miscarriages because of it?

My mom literally just sent me an article about Rh negative and it got me thinking. It said that it causes your body to fight off a 2nd pregnancy and it tends to be a lot more difficult for people who are negative to stay pregnant.

I had to get the rhogam(sp?) shot with my first child bc she was A+ & I’m A-. I miscarried my 2nd child but I didn’t do the testing to find out why but my husband(not my 1sts bio dad) is positive also.

Part of the article is posted below.
