Hi there, last time j got my period was last month but before that it was in Febuary. Me and my partner have been having sex every weekend Friday-Sunday since Feb with no protection. Ever since Saturday I've been feeling really weird, like REALLY tired, even when I wake up I just fall back to sleep. I get really moody even when my partners just talking to me I start arguments but then I get all happy again. I get constant headaches during the day which makes me a little dizzy. I get a tingling feeling in my breast which sometimes gets painful. I get pain in my left side of my stomach. I really don't know if I'm either pregnant or not. Please help me?
