Thanks to those of you that responded to my earlier post. Had a monitoring appt. today and all is well. Lining is already back at 7.9 TL and E2 is in the 1300's. Transfer should be in just over a week so looks like all is well and we are good to go! Whew! Now I can just start obsessing about the 2ww! Thanks, again.
That's some fast building going on! It's just one of those things that happens I think (breakthrough bleeding), glad you are on track for a fresh transfer.
