Has anyone's titer D gone up? I'm RH- with antibodies. Because I'm B- and hubby B+ docter says our blood types don't match. So my titer D went from 256 and now it's 512. I just hit 18 weeks. I had still born in July. So I'm hoping to get insight. Talk with anyone if they ever had this problem  Have no family so can't talk to anyone and Hubbys family can care less.
