Antibody issues!? Sorry so long

Heather • Greyson Benjamin born 4/6/16... Little boy stole my heart 💙
10w, 3d coming through one of the roughest weeks in my life. Long story short, Sunday was an emergency to trip to the hospital. Bleeding bright red blood/clot. Everything was fine. Got my first us! Baby's hb was 165bpm, pelvic was good, hcg levels great. Had follow up (original ob appt) on Wednesday. Dr said nothing to worry about. Baby was right on schedule (little ahead where we thought), everything looked great. No fears. Then today, I get a call that my blood work has an issue. I'm going to sound stupid, but I was honestly just almost shutting down listening to her talk. She said that my body was producing antibodies to a protein that baby was producing. I'm 99% sure she never said anything about the rh factors. It was a long medical term.. The last word was just a letter (b/e?). She said they were sending me to a high risk specialist who would assess me more. That I would be monitored every 4 weeks on my levels. She did said that while I was elevated, it was still low (a 4) and that the baby was measuring perfectly. I'm just freaked out and hoping someone has any advice or info for me. Has anyone here been through this before? Picture of my baby gummy bear ❤️
