After 3 losses we were referred to a fertility specialist. He found one of my thyroid antibodies was very elevated and causing my miscarriages. He put me on 25 mcg Levithyroxine before BFP and baby aspirin and progesterone through the first trimester. We had our rainbow November 2016. Just got a very early faint bfp at about 11dpo. Had hcg blood done 12 dpo and it was at 10. Went today for a recheck on hcg and waiting for results. Im still on the Levithyroxine for the elevated thyroid antibody, but Im totally nervous. I know we were blessed to have our daughter at all, but I just want 1 sibling for her Earthside. Anyone else in a similar boat? I know it can be hard to be in a thread with people who already have rainbows and are hoping for another, but if that you, youre definitely welcome here too! Sticky dust to all the May Rainbows!
