I am 20 years old. I used to have my period regularly but this month, I didn't have it on May 1 when i am supposed to have it. I never had sex in my entire life, not the actual penetration. My boyfriend and I can get intimate from time to time but it never came to the point that an actual penetration happens. We just do dry hump and that's it, I never take off my clothes. I am worried I might be sick or there's something wrong with my reproductive system. Or if it is possible to get pregnant with dry humping? However, I can say that I'm getting pretty much stressed with my internship right now. My internship started last January but my period for January-April was normal and regular. This month was the only problem. Could this be just because of stress and my anxiety that I didn't get my period? Please help. I couldn't talk to anyone about this. Thank you so much!
