am I prego?


last month when I was no fertil my bf and I had unprotected sex but I got scared and we stopped before he was able to finish. it didnt really last long either. the next morning I took a plan b and we didnt have sex after that. after my period was 3 days late I took a test and it was negative. now I'm 8 days late and I took a test yesterday and this morning and both came out negative but I still havnt started so I'm not sure if I should worry or not. I dont want to be prego but what do yall think and what should I do?? I also feel no signs of pregnancy nor that I'm about to start my period. I'm freaking out.
