hello! i need some help! i had unprotected sex on December 4th and then i had what i think may be a period but not sure. it only lasted about a day and a half. for the past 4 days i have been extrememley exhausted and nauseous. i took to tests and both came out negative. im still so very nervous. did i test too early? this saturday (the 25th) it will be exactly 28 days since i had unprotected sex. what do i do?
let me rephrase that a little bit. what i think may be a period started on the 18th that night and only lasted till monday morning.
