Me and my bf had unprotected sex on the 7th of December. Starting last week or so, I've been waking up with nausea but no puking ... I have to pee a lot now.. And I feel dizzy and always moody.. AF was supposed to come last week. Took a test an hour ago .. Saw a dark blue line then next to it a very faint line.. Also I have dark nipples now... Going to retake on Saturday
