Appetite loss ?

So here's what's going on ladies. The last few days I've had a hard time eating , I'll be craving something but if I don't go get it right away i get sick . Let's use last night as an example , last night I wanted a chicken wrap from Dairy Queen SO BAD , I waited a half hour before I went to get it and by the time I got it and ate it I was sick to my stomach , I felt so nauseous. Even right now I want chocolate so bad but I can't decide what I want and it makes me cry , and also last night (I'm a big pickle eater) I ate a pickle last night and I couldn't finish it .... it seemed way to sour ! Same problem with ketchup and they call me ketchup Queen because I eat ketchup straight up ... it seems way to salty to me now . This never happens to me . I'm not due for my period until the 17th of July . And also I don't seem to be ovulating ... I took an ovulation test to see if I was and apparently I'm not . So I'm very confused inputs please and thank you !
