Anyone here have negative blood type with a so that has positive? I'm B negative and my husband is O positive. I'm wondering how far into your pregnancy do you have to worry about the antibodies? I'm 11+2 weeks with no problems at all but wanting to see if I still need to be hyper aware if anything does go wrong. Or just your experiences would help make me feel a little better :/ my blood type is rare so it worries me :/ any stories please??!!
