FET Ovary Pain

*S*E*C*O

I am in the midst of an FET cycle but am still at least a couple of weeks away from what would be the transfer date (haven’t even started PIO yet). I’ve been on low-dose lupron and increasing number of estrogen patches for about two weeks. For the last few days, I have been experiencing fairly significant ovarian pain, similar to what I feel around the time of ovulation. Has anyone else experienced this? If so, do you know what the cause was?
