Anti M positive from blood test

Melanie

I went in for my 12 week visit today and the midwife said my bloodwork came back that I was anti-M positive. Has anyone ever experienced this or heard of it? My sister and MIL are both nurses and had never heard of it and my husband is a PA and hadn’t heard of it. Apparently it is only a concern for the baby if both you and your partner have the anti M positive antibody so my husband is scheduled for bloodwork Friday
