Disney - to be honest, I believe that what you think is feeling AF coming, is in fact caused by the progesterone support. Pessaries, crinone etc, will give you a feeling of AF-like crampiness. I noticed it this time before I even had the transfer.
Toni - wow. I'm sure it is possible. Had you had a BT to confirm hcg was back to 0 after your ectopic?
