I am 47 yr old female, 5'3" 110lbs., general health is good, have good blood pressure and great cholestorol levels. My issue started three weeks ago on a Thursday, I had cramping and pain in stomach right around belly button, this lasted for three days but pain subsided when my period came, which happen to be three weeks late. Then the very next Thursday I woke up at night with the same pain that finally subsided on Sunday, now here it is again Thursday the pain is back and I am spotting, it seems if I drink Pepto and put a heating pad on my stomach it relieves the pain somewhat. Is it possible it is an ulcer or a female issue?
