Is losing your appetite a menstrual symptom

Well I already did a pregnancy test .. All negative. But now I still can't figure out why I'm losing my appetite like as soon as I get ready to eat I lose it. I was wondering was it a period symptom cause this never happened to me before. My stomach hurts but not cramping. My boobs are getting big. But I remember this happened before and I got my period the next week. But the only difference is losing my appetite. I don't crave sweets like I normally do. I can't even eat bc I lose it and I know I'm hungry
