First FET next week- major cramping

Hi All,

I’m preparing for my first FET next week. I stopped Lupron and around the same time started estradiol injections. I’ve been experiencing a lot of cramping similar to period cramps. Mostly just very uncomfortable. The doctor was surprised when I told him and said it probably has to do with my endometriosis. I start progesterone shots in a couple days and we are hoping that counteracts the estrogen and my cramps subside. Anyone else experienced a lot of cramping/pain from estradiol?
