Any advice please?

Af not due for 18 more days. My lmp was April 16th. Lasted maybe 5 days. Usually it's 7. For the past couple days I've been having cramping type feelings or kinda like a sharp pain every now and then in my lower abdomen it's not on either side it's in the middle. If I do something like bend over or something like that i get a weird feeling. I've recently started breaking out (acne), my breasts aren't sensitive but sore feeling. I have noticed a slight change in my belly's appearance I was thinking it was bloat but I can go without eating for a day and it'll still look like that. I say go without eating cause I've been nauseous and haven't felt like eating a lot.
