Am I pregnant or just freaking out?

Kailey

1. My usual cycle is 28 days. My period is late by 8 days.

2. I had sex on days 16-19.

3. The app says I’m on cycle day 38.

4. I haven’t taken a test yet.

5. I did not take plan b. I am on birth control but that isn’t 100% effective and I had messed up my days with it that week.
