Chances of me still being pregnant after 5 negative pregnancy tests.. no period for 2 months was on pill for only a month then stopped?

Probably not: When I was very young my mother told me that pregnancy can occur at ANY time under ANY circumstance. That's why I then just studied a lot. But five negative tests, well a pretty sure bet you're not pregnant. If you want to be absolutely sure, a blood test would cinch it, but that's probably not necessary. And...those pills can have an effect somewhat beyond the time you stop using them.
