Hi. I had menses last August 10. I had contact from August 18 to september 9 and we used the withdrawal method. However there was one or 2 instances when my partner wasn't sure if he withdraw at the right time before anything comes out from him. I was supposed to have my menses on september 10 because i have a regular menstrual cycle. However, i only menstruated on september 26 which is 2 weeks delayed. I did PT on september 20 it was negative. Then another PT on october 10 and it was still negative. I don't have any menses last october up to now it's already november 2. Am i pregnant? Or just having a delayed menstruation? I was actualy stressed few days before september 10 because my husband left to work abroad. Please i need an answer..
