Hi Im 18 years old, First time poster on here but im in need of serious help before going to a doctor (they freak me out)

First of all PREGNANCY IS NOT int he picture...need sex for that...

In March of 2007 I experienced a VERY bad unusual period I followed up with my doctor as I was due for a smear anyways...she said nothing felt abnormal Not even 2 days after my period I started to get really bad acid feeling in my stomach I let this go on until JUNE non stop, nothing helped. It went away on its own In august I got another bad period and stomach pains back again, Followed up with my doctor in September she said my gut was "Inflammed" gave me 2 weeks of Pantoloc (was sample packages) Which did nothing but make me TIRED...Here I am in november stomach pains that feeel like a balloon filled with acid being twisted adn now my boobs are bruising, just from wearing a bra I've also gained about 40 pounds since march which isnt normal. I've tried cutting dairy out of my diet, eatting small meals, even taking extra vitamins. NOTHING seems to help and Im ready to DIE!! Anyone experience this? Any advice before I call the doctor? I would at least like to know somethings To be tested or ask about

Thanks in advance

Jessica
