while I was 14 I had my first period, at my first time(s) I used to bleed almost for 10-12 days. But I was always so irregular. After having sex at age of 16 my period went smoother and I used to have my period every once in 1.5 to 2 months for 5-7 days. Then I came to one of the coldest reason in united states, and now I never have my period usual. Always random in every 3-4 months. I am worried. I showed up to doctor she said it might be because of change in place or may be because of worrying a lot. My mom also bleeds a lot as far as I know. And the cramps almost kill us on our 2nd day of period. I started taking equiline pain relief and now its been almost 5 months I am not having my period! I am not pregnant but my breasts hurts (feels heavy, irritation around nipples, don't even feel like wearing a bra) almost everyday. I also have light pain in my lower abdomen(left or right) sometime! I think of going to doctor but I work a lot so I have no time seeing a doctor.. please help me out. I am infertile?
