Period pain so bad

Hey guys, so few days ago I woke up to really bad stomach pains and gathered I had started my period, I hadn't so went back to bed and tried to go back to sleep when the pain got worse and worse, the pain got that bad I was physically sick but then that made the pain even worse to make me sick again (was like a vicious circle)

During that day I finally got a call back from my doctor to give me strong pain killers as this pain was so bad I couldn't even move.

Yesterday I woke up and my stomach was so swollen I felt massive and my stomach was so tender to touch, even little things like bending over was sore,

Today im the same just stomach not as swollen but still a lot, and can't move around unless I'm still on these strong painkillers.

Throughout these the days the bleeding hasn't even been so heavy, not as heavy as I have had them, but I've never had this much pain from a period, in fact i have never been in so much pain its made me sick before.

Has this happened to anyone before?? And help will be appreciated, I can't get into the doctors till the 28th :(
