My cycle is usually pretty regular, and never more then a week late. It's currently 5 weeks late. I'm freaking out. I've never had sex or done anything with a boy. I'm 15 and I've had my period for about a year now. Is there any possible way I could be pregnant? And where tf did my period go. (It's funny how we hate periods so much untill they don't show up one day😣😣😣) please hellllppppp.
