I'm a teenager and I need some help figuring out if I'm pregnant or not... So my boyfriend and I have had sex 4 times since the beginning of the year. January 28th, February 14th and 20th and and March 16th. January 18th I got off my period and February 7th I got my period so that was 19 days between my period and I ended that period February 14th and that's also the day my boyfriend and I had sex. We're always safe and use a condom and he pulls out before he cums because I'm not on birth control and my parents would kill me if I get pregnant but February 14th he put his penis in for 5 seconds without a condom just to see what it felt like and he pulled it out because he got scared. So that next day I took Plan B That be bought because he was too nervous and I ended up getting my period AGAIN 5 days later and that period only lasted 5 days. I got my period 10 days later on March 6th and my time between my period is usually longer than that but I use the app the Period Tracker which evens out the days between your period and that's how it predicts when your next period will be. I was supposed to get my period 2 days ago and I still don't have it so I'm not sure if it's because the days are off between my period on my Period Tracker app or not. I had sex 10 days ago safely with a condom and he puLled out each time as he usually does and he said hes not worried because we were safe and if he was nervous he would get me Plan B like we did last time. The only thing that has changed about me is that my boobs have gotten a little bigger but they're not sore and sometimes my boobs get bigger from my period or before I'm going to start. I'm really nervous and I was wondering if i could possibly be pregnant or not and someone PLEASE help! I hope I gave enough information and sorry about all the dates. And one more thing is that I've been sick for 10 days now with a fever, chills, aches, and swollen glands but it's from mono so I don't know if that could be messing with my period cycle or not either. Please help! Thank you.
