I'm due to start my period in 5 days ( I'm not on contraception)

Now about 3-4 days ago I had the worst cramps imaginable, I was rolling around on the floor, running back and forth the toulet and felt like a massive pressure and shooting pains down my bum. Which took about 45 minutes to ease off

I have a severely retroverted uterus so I figured that must be what's hurting.

My stomach is very boated and sore to touch! sitting down is painful too. It feels "swollen"

Now today I've been having shooting pains which were all on one side to begin with but I had the odd one or two on the opposite side.

I would also like to add that I experience sickness this morning, which lasted about 3 hours.

I've never felt like this before my period before, I feel drained.

Has anyone else?
