Endometriosis ? Possibly please help

Ch

So I get those super bad butt cramps when I ovulate it’ll start from my ovaries and ends at like the rim of my butthole . I’ve had this every month since I started having periods when I was 12 but it’s hurt for a couple mins to a hour and it’ll have me in my toes sometimes . Can someone please tell me this is normal I’ve been ttc baby #1 for 4 years now with only 1 chemical miscarriage.
