I'm 15 years old, and I've had my period for about three years. Each month it would come after exactly 28 days or a couple of days after that 28 day mark. The last period I had was in April, and May's period was totally skipped. So this Sunday (June 10) it will be exactly 8 weeks since I've had my period, and that would be the day it is supposed to come if my cycle had been regular last month. I'm worried because I've never skipped one before. I have a boyfriend, but we've never had sex. In fact, we've only kissed and had our shirts off, so pregnancy is definitely not the case. My mom told me it was because I was stressed over finals for school, but I'm not too sure because I never felt anxious or stressed last month. I'd like to know what kind of things can cause you to skip your period besides pregnancy. Also, will I get my period next month and will my cyle go back to normal? Thanks.
