ummm I need help I think

Hi I’m 15 and I’m just giving myself a lot of anxiety over this

My boyfriend and I had sex but he didn’t go fully in like it hurt so I pushed him out so he barely went in, he cummed after (not inside) and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says that my fertile window closes in three days... is there any chance at all I’m pregnant, I know precum can carry sperm but that’s only if you cum before hand, I don’t know, a lot of things are really new to me and I want to minimize my anxiety so if anyone could please help that would be so so great thanks.
