Thanks vel, gina, and jez. I called the RE this morning and we're going to start betas tomorrow to monitor my hcg, progesterone, and estrogen. RE will call me tomorrow night with the results. My P was at 14 on Thursday but should be over 20 now that I'm pregnant. If it's low, they will up my dose. I guess the hope is that P and E I'm taking will help even if my thyroid isn't quite right just yet. I can't explain it, but so far I have a good feeling about this one. Fingers crossed!
