I'm 11wks with my 3rd child and I just got a call from my dr office saying I tested positive for an anti body in my blood. They said its a very low amount but they wanted to let me know because they will be drawing blood every visit. :( of course I went to the Internet and read a bunch of stuff. Anyone else in this situation? I've never dealt with it and honestly am a little scared. My dr said that I shouldn't worry and they will monitor me very closely.
