Urgent Help!


Hi guys im new here and this app has really proven helpful. Although i cant figure out one thing, i would appreciate any help i would get. I started my period on the 16th night around 11:00pm but dont know if i should consider it as first day of my period. I was done with it on 22nd that is yesterday. Now my husband and i wanted to have sex without condom but the app tells me i am fertile and 7% chance of pregnancy. I dont want to get pregnant as we are not yet ready for it, so can anyone pls tell me if today would be a good day to do so without having the risk of being pregnant??

Thanks a lot for your help and i really appreciate it :)
