Weird period problems

Ev

Lately my periods have been very irregular and late. I have been late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> by 11 days. I know I’m not pregnant because its been a while since I last had sex. On the 15th of this month during the day I decided I was safe so I didn’t have a pad on. I was feeling uncomfortable so I went home and I was bleeding. I thought “Cool, I guess it starts now”. I wear a pad overnight like always and I wake up and theres NOTHING. Two days after still nothing. I don’t know what to do and I’m confused. Has anyone else gone through this?!
