Help!

Ok so I’m conflicted with what’s going on to my body right now. Last week I was extremely nauseous and would throw up anything I ate and it’s still like that but not half as bad. My period was suppose to be here Wednesday and normally before my period my boobs get extremely sore and feel like rocks and the only thing going on with my boobs is that my nipples are extremely sensitive to the touch and I’ve been having slight cramps on and off these past couple of days. I don’t know if I should think I may be pregnant or just wait a couple extra days to see if AF is just late. Does anyone have any advice for me? It would be greatly appreciated!!
