I’m seven days late on my period according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and I’m a sexually active person. Everytime I’ve used a condom and the last time I had sex was November 5, so according to those numbers I should be coming up on 5 weeks. I’ve had no symptoms besides sore breasts and that was only last night, I haven’t had anything today. I do drink a lot on the weekends and I read that will effect your period too, but I’m not sure what it could be, especially since I’m not on hormonal birth control either. Help.

Update: I took a pregnancy test and it was negative
