Dizziness is it normal?

My periods usually last about 4 days.. But I've never felt the way that I do now (Age 27) from when I was 18.. No symptoms at all. But I believe I feel this way (Dizzy, out of it, cramps here & there, bloating, hot flashes, and a very high desire to eat like a pregnant woman.. Lol) because of my age & no longer exercise?? HELP!! IDK WHAT IT IS..🤔😬
