Option to choose that I'm a virgin.

Hii :) I'm new in the app and all. I just need help with one thing? I'm 20 yrs old and I'm a virgin. However the app doesn't have the option for me to choose that I am one. My period is about 2 weeks late. But the app automatically says I'm pregnant? I am in a relationship but not sexually active. So is there an option in the app wherein I could choose to say I'm not sexually active? Also, it would be great to add that option if it's not available. Love the app though!
