So a week ago I almost had sex with this guy. All he got in was the tip, but we didn't use a condom, I know so stupid I feel ridiculous. And now even though he didn't even get all the way in and didn't cum I think I could be pregnant, because according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> my period was supposed to start a few days ago. I have no idea what I'm supposed to do now.
