Tomorrow marks a week since my gf missed her period, she was supposed to start on the 16th/17th. We had sex 2 times in the month of Feb and I used a condom and pulled out before i came both times. She has taken 4 pregnancy test, all on different days and all negative. She does have a history with irregular periods, about 2 years ago she missed 6 months due to exercising to much and not eating enough but she has been fine until now. She did start running again this month and has been kinda stressed because she had testing and instrument competitions. I wouldn't usually be as worried be she has been experiencing symptoms of her period but has not had it, sore boobs, bad cramps, kinda tired, kinda emotional, and bloating. I've tried being patient with this but I'm not sure i can take this any longer. Not looking for any definite answers, just what you think.
