Well My period was supposed to start three days girl. And I want back and looked & counting the days between periods. & it's 28 days... And I always start my period when I'm supposed to start. & it's been 30 days today! & I still haven't started yet! People tell me to wait a couple of days to see if I start my period but I kinda think I mite be pregnant but idk... I don't want to jinx myself because me and my boyfriend been trying to have a baby for two years now.. Should take a test now or wait like everyone telling me too?? Is there anyone that's been through what I'm going through right now??
