Unless you've had a penis or semen in or near your vagina, you're not pregnant. Virgin birth is quite uncommon these days.
OP your 17, your not going to be totally regular yet. There are woman who are in their 30's who still aren't regular. Take a test to ease your mind then just wait for it to start.
i hear ya on that, my period is dead set regular- no if ands or buts... and the 2 times it wasn't...well, now I have twice the love in my life just take a test, chill out, everything will be fine
WOwww at this thread. Your just late. It's EXTREMELY common and there is absolutely nothing for you to worry about ( since you've never had sex). The best thing to do is yes, go to a doctor if it doesn't come again. You said you experienced some blood, which is called spotting, and sometimes that can occur when your usual full period does not. I'm sure your fine.
I think someone needs some sex education from GI Johnny... https://www.youtube.com/watch?v=NyQtuCKXPc0
if your worried about your parents finding out or something just go to your mom and be like "did you ever have spotting when you were my age." It could just be your body. i've had spotting and i've never been pregnant.
Did the guy touch his dick before he played with you? This is an extremely unlikely way to get pregnant, but it is a remote possibility. It is also a good way to get an STD, which could explain some of your symptoms. Most likely your body is just reacting to stress, but only a doctor can tell you for sure.
