FET: I’m getting nervous to transfer…

I have a transfer coming up in two weeks. Just did an egg retrieval two weeks prior, got my period and felt fine. Now that my period is done, I’m still having this cramping in my uterus like I just had my egg retrieval yesterday. I’m going to the doctor for my follow up before transfer on Friday, so I will ask her but has anyone ever felt that way a few weeks after an egg retrieval? I’m so of nervous to transfer if my cramps don’t subside. I need this one to work so badly. I also have bad circulation and my body runs pretty cold. Any suggestions on how to keep myself warm leading up to the transfer? My feet and fingers are freezing.
