Okay so I've had unprotected sex. But not once has he came inside of me or on my body only my mouth (sorry if that's tmi but I'm panicked). My period is now two weeks late. And then I stress about it so my period becomes even later. I genuinely feel like I am not pregnant so I want to just wait it out for my period but I also am afraid that it will not come. When do pregnancy signs start to show? What do you think I should do?
