Around and above my belly button, sides and around my ovaries it feels like little tiny bubbles? I have taken alka sezer, gas-x, pepto ? It has been going on for 5 days in a row? Mainly when i am sitting down. It does not hurt it is the strangest feeling? My stomach also gets really warm at times? What could this be my period is due on the 24Th of this month but I have never had these kind of feeling in my stomach Has this ever happened to anyone? I am 43 could it be a premenapause thing?
