Concerned about my period

Julia
Hey guys so I haven't had my period since the end of March (<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I haven't had a period in 37 days) I had a boyfriend but we broke up and we were never had sex. (I'm a virgin).  We made out a couple of times without our clothes (my underwear was on, his were off and our "areas" weren't even close to touching) and he never "entered me". He never "came" either. I know I can't be pregnant. Should I talk to my doctor? 
Please help me guys I'm so scared
