So me and my ex had sex exactly 2 weeks before i had unprotected sex with another guy i like. Not knowing if i would get pregnant or not i waited 2 more weeks n a day before me and my ex had sex again. I wanted to know could i b pregnant? How long does it take to form? I have been off depo since the beginning of the year n still no period. A week after me n the guy had sex i had some brown spotting, feeling tired alot, wake up daily with a headache, and have mild cramping every other day.I also took 2 test saying negate. It has been 1 month so if i am how far would i b?
