I'm 14, I lost my virginity to my boyfriend of 5 months on April 22nd, 2015. We used a condom and checked it to make sure it wasn't ripped or anything. He pulled out and I was getting pretty paranoid so he filled it with water for me and nothing came out, therefore the condom was perfectly fine. However it's now may 4th and I still haven't gotten my period. The last time I got it was April 7th. I usually get it on the 25th or 26th day, sometimes even the 24th. I've had it for a little over three years and it's still not completely regular. Anyways I usually would've gotten my period by now, I am so scared that I'm pregnant but I have no symptoms of it. I've been so stressed out this entire week, I've even bawled my eyes out because of it, I truly don't want to be a mom. I'm not on birth control and never took the morning after pill. My sister is a senior in high school and lost her virginity junior year (so last year), I talked to her about it and she said sex can delay your period. Her friend had sex with this one kid and didn't get her period for 5 months. So why is that?!?! I really just hope I'm not pregnant! And I'm ready stressing about it too, very badly. Can that delay it too?!? The weird thing is, that I've been finger** plenty of times by different guys and my period was always fine. What's the difference with a penis?? Thank you so much, PLEASE HELP :)
