Pregnant or messed up period??

Okay so this eve app is almost always accurate about my period. I usually have my period every 14-17 days.

My boyfriend and I had sex with a condom and he came. He took it off and we laid there for a few minutes then he went in me raw for maybe 2 minutes, but didn’t cum.

Well I’m late on my period and usually I’m in sync with the app..

Do you guys think that maybe every 14-17 days is too often and my body is adjusting or do you guys think I’m pregnant?

No judging please... just help us all I need
