I just wanted to join in and wish you luck and say it's natural to be scared and anxious!
I suffered an ectopic pregnancy at 9wks a few months ago, and lost my right tube. Sadly my left tube is in bad shape and we've been told to go to IVF, and are just starting our first cycle.
I am excited about trying and really want to be pregnant, but I am also anxious- what is something goes wrong again? What is IVF takes a long time to be successful? etc etc
Hang in there, highs and lows are to be expected.
It's not easy, but you'll get there. Keep positive. Good luck.
