so i missed my last period and i was stressing out about it so i took 2 pregnancy tests and they were both negative, still didn't start. a week later i took another, still negative. so now it's been almost a month and i still haven't started. i was super stressed and emotional the week before i was suppose to start my last one, and i know that can effect it. but any answers to what might be going on? i'm really starting to freak out!
