am i pregnant?

So i havent gotten my period yet. I was supposedly was gonna get it today. My cycles usually last 36-38 days. And the days with hearts under it are the days ive had sex.

For the past 2 days my nipples have been hurting and i have cramps but they arent that bad.

I let my bf go in raw but then id have him pull out a couple sec after he puts it in. Bc he wants to see how it feels

We always use condoms. But im really nervous that i might be pregnant. Like ive mentioned my cycles only last 36-38 days.

Im only 16 i really really need some advice or answers😭. I am not trying to get pregnant

Update i went to the bathroom and i wiped and this is what was on it. What does this mean?? Is a good or a bad sign?
