Day 15 Recovery from lap assisted vaginal hysterectomy

Hi I'm new but this site looks amazing. I had a lap assisted vaginal hysterectomy and he took out what I had left one ovary, uterus and cervix a d started me in estradiol patch immediately after. I was woken out of sleep with swelling across my belly and stabbing pain around my belly button and the most incredible itching across my belly. I look in the mirror and I look very pregnant . Each day I walk as doc told me and each day I swell and look 6months pregnant. I'm thin but good lord I'm swollen. Thank you in advance for your thoughts.
