sooo i've been having unprotected sex with all of my boyfriends for the past 7 years or so and I've never been pregnant.. when i was younger i had really irregular periods i even went 6 months one time! but i took 1 month of birth control and started again..but wasn't really that regular up until the last year or so..which i still have been having regular unprotected sex and still not getting pregnant. but this month i'm at least 2 Weeks late now..which kind of concerns me cuz i have been so regular lately. i took a dollar store test about a week ago and it was negative and one a few days before that which was negative too..do you think i still might be pregnant? i spotted like 3 times only lasting a day or.2 each time and i feel like i'm gonna start but just keep waiting for the blood to come and nothing.
