So yeah, I'm now having panic attack since I'm currently 5 weeks and 1 day late on my period, which never happened before. my last period was september 14 - september 20. My boyfriend and I had sex on october 13. He used condom and pulled out before he cum. Since then I still haven't gotten my period. I tested on my 4 weeks late, but came negative. I don't know what I'm gonna do, I'm freaking out. What supposed to be the problem? Is it still possible that I'm pregnant ?
