Ok, for the past few months Ive been havin some crazy things going on with me. Lets start with Jan. 30th I started my period and it lasted its normal 7 days(ending in Februrary), about a week later I had unprotected sex, then at the end of Febuary I started a second period that also lasted 7 days. So, Im not even sure when Im suppose to start again, Im guessing March 24th. Now for the past couple of weeks or more Ive been experiencing stomach pains(mainly upper, right below my breast), sweet and salty cravings for breakfast (which only happens on weekends cause I work and only wake up in time for breakfast on Saturday & Sunday), my breast hurt off and on, I have diarrhea after I eat, I smoke like 1 or 2 cigarettes a day(use to smoke way more) and when I smoke it upsets my stomach sometimes and when I dont smoke the smell upsets my stomach, moody, little emotional, fatigue, this past weekend I started feeling a little dizzy/faint if I stood up to fast or until I ate something, back pains, and weight gain. I was on birth control for 6 years and stopped taking them 4 months ago. So I dont know if the weight gain is from that or if I am pregnant. Please help.
