unknown pains, please help

S💎
So im having pains in my uterus area and im not sure what it is. 
I finished my period last week and the pains arent the same as my period pains meaning theyre not cramps. This pain is continuous and very sharp. I cannot sit up right or even stand but all i can do to make it stop is crawl up into a ball. 
I checked google and it said it was something to do with polycystic ovary syndrome, can anyone let me know what this is because i am not sure.
