Do you think you could not be pregnant. I know with me when I am on the pill my period is light and when I am off the pill my period is really heavy and abit painful and some months a few very small clots. I get headaches also and it is much much heavier then they are when I am on the pill. Maybe it is your period and its really heavy in comparison as now your not on the pill. I hope you are ok I can imagine how scary it must be not knowing whats really going on and having no one to talk to. Can you see a family health nurse? They could do a pregnancy test and confirm if you need to see a dr for more tests or if its a heavy period. They are not aloud to disclose your information to anyone so it would be confidential. Thinking of you. I was pregnant with my first at 16 (had her at 17) my parents didn't know I was pregnant till I was 6months (had her 11weeks after they found out) as I was too scared to tell them. My mum guessed before I had the courage to tell her.
