Had IVF on 2/15/10. Three day 5 blastocysts were transferred (B/b, B/C). Felt: very thirsty and cold, had some night sweats in the first three days. Today, day 4 post-transfer, had a horrible headache and no matter what I ate, was still hungry. I had some pinching (!), cramps (?), but not sure, because somebody at work said she had that after her IUI. Woke up at night to eat. Still thirsty.
