Welcome to Healthcare Magic!
It seems you have two problems simultaneously.
An acid peptic disease
in the back ground, and a prementrual syndrome during periods.
Your symptoms other than the pain abdomen are from premenstrual syndrome
and pain abdomen occurs due to stress
aggravating the back ground acid peptic disease.
I would suggest you to get a treatment for both the problems and hence please consult a gynecologist and a physician of you locality.
With treatment the problems would resolve soon.
I hope the advise would be helpful for you.
