Just popping my head in to wish you all the very best for your BT ladies!

Bianeczka, I don't know if the cramping is to do with with endo or not, but I had cramping on and off during my 2WW and of course I thought AF was on her way, but I couldn't wait and I tested 11dpt and I had my very faint line. My BT was scheduled 5 days later but I already had an appointment with my FS which I made weeks earlier in case that transfer didn't work and the FS did the BT then and there and I got the good news that night. GL sweetie, I hope you get your BFP!
