@Barca07: yes, sorry to hear about the chemical. It took me a LONG time to get over the grief. I don't think i truly am over it but just focus on my current bub atm. As my FS said, the good news is that you know you can fall pregnant.
Pregnyl is a good addition just in case. I thought your P4 was quite low last time. I saw your other post. I threw every in for our last biological embie, including endo scratch. It didn't do anything. FS said that there is a controversial of when it needs to be done. New research suggests that the closer to the AF time, the better. Most FS just do it at the traditional CD21. She left it up to me to decide to do it or not. Since it is such a hassle for me to arrange it here in Perth and it is such an invasive procedure, I skipped it for this transfer. I know most ladies have done it in and out without sedative. The FS, who did mine here in Perth, put me under and i was bleeding quite a bit afterward. As for embie glue, it is not exactly a "glue". It is a chemical that is more receptive to the endo lining. I don't know how effective it is. It is non-invasive so you might well pay the $350 and get it.
