I'm relatively new to these forums............but really getting a lot out of reading the various posts on here! Thank You Ladies! We have been TTC for 18months with what the disgnose as unexplained secondary infertility, 1x IUI (cancelled cycle), 2xIVF (1 ET - BFN, 1 cancelled just before ET due to OHSS), 1xFET (awaiting outcome). Well my husband and I had our first FET last friday...........so now the waiting game is here! We had a fresh IVF ET a few months back now but it was a BFN. This time 24hrs after the ET I experienced really uncomfortable cramping and got quite concerned, it lasted about 5 hours or so and then went away completely. No pain at all since. Previous ET (fresh IVF though) I didn't experience any pain or signs at all. This time out FE is 6-7 days mature already - don't know if that has any effect on what I experienced. Has anyone else had an experience like this? I have read that others have experienced cramping after ET, but that seems to be with fresh IVF ET cycles and possibly due to the follicles filling back up with fluid causing the cramps. I was hoping it might be a good sign this time, something may have been happening.............well I'm hoping it was anyway
