So since I started having periods at 13 (I'm now 20), I've never had a problem with irregular cycles. It's never been more than a week late.

However, my last period ended around October 13th (7 weeks ago), and I'm still waiting for the next one. While I am in a relationship, I am also a virgin, and to make pregnancy even further impossible, I am studying in Europe right now, and thus have not even kissed someone since I saw my boyfriend in August.

I'm guessing the lateness has something to do with the environment change, but I arrived in Europe in late September and my October period was on time. I feel like if anything, my period should have been late then since I was much more stressed out at that point. Should I be concerned that it's this late? Or wait a little longer?

Thanks for your help!
