Hi today is day 8 of IVF stims. I m on Gonal F 375iu and started Cetrotide 3 days ago. Today at ultrasound there was fluid in my uterus that wasn t there on scan 4 days ago. I ve been told to continue stimming and they will monitor me but if fluid doesn t go away and I make it to egg collection any embryos will be freezed. What causes fluid in uterus?! I have had a lap and dye test and showed a blocked tube but they did nothing about it. This is second IVF first Cycle failed. I m so upset can t stop crying. Is there anything I can do?!
