missed my period..could i be pregnant?

addie

a couple weeks ago i was with my ex boyfriend and we had sex without a condom. him and i weren’t thinking about it at all since we were in that state of mind. we had sex three times that night, all without a condom, and using the pullout method. i already knew what we were doing was not going to end up good since we pulled out every time and didn’t use a condom. the morning after we had sex i logged onto <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> to see what was going on with everybody when i saw my fertile window was open. i already knew what was happening and immediately threw up. i was terrified so i told my mother what i did with my ex. her being the caring mother told me she would get me plan b and everything will be okay. i took the pill and felt fine over the course of the weeks. my period usually starts in between the days of the 11th through the 15th so you probably can see why i’m freaking out if the plan b worked at all. my mother said she would get my a pregnancy test in the morning since peeing on the stick in the morning gives the most positive feedback. could i be pregnant?? (please be nice, last time i did one of these for the fertile window i got so much hate so please don’t be rude, thank you).
