hi i am 19 years old, i have been on birth control for 5 years, 2 months ago i stopped taking it and kept having sexual intercourse once or more a day with my boyfriend of 2 years, my last period was a day late and only 2 days long which has never happened, usually i have a 7 day period. i started my new pack of pills when i was supposed too and now 6 days before my next period i started spotting really pink blood along with cramps, i have been very dizzy, bloated, and just today crying for absoloutley no reason at all, urinating a lot and nauseas. Also for weeks i have been very, very tired , can all this mean i am pregnant?
