I'm 20 years old and am two months late for my period. I have done extensive travelling through Europe for two months recently. I missed one period while I was away and another right after I returned home. (Consecutively). I have never had sex, but did fool around with a guy once while in Europe. I had my clothes off and he was supposed to leave his underwear on. Drunk unsuspecting me thought he did. Apparently he had taken them of and I was unaware. (I know I'm Naive...) I have very high anxiety and stress a lot about everything. I also have high blood pressure (about 160/120) which my doctor is aware of. Could I be pregnant or is my nonexistent period just be caused by stress? What should I do? Majorly freaking out.
