Pregnant with cramps

I keep having these sharp pains in my uterus. Not like period cramps. It happens a lot when walking or bending. Is my uterus just adjusting and growing? Also my pain is on the right side sometimes, near my ovary would be. Anyone else have this? My positive test finally just now showed up 8 days past my expected period. So I'm worried something may be wrong since it took so long to show up. Idk I may just be paranoid lol
