Just the tip for a few seconds during luteal phase pregnancy risk? Please help

Hey everyone,

I’m a bit stressed and hoping for some clarity.

What if just the tip was inside for a few seconds while she was in her luteal phase? No ejaculation, and it was only for 2–3 seconds.

I don’t track ovulation, but I’m pretty sure it was cycle day 26. Her usual cycle length is around 31 days. Her last period started on Jan 24, and this happened on Feb 18 around 11 PM.

There’s no way ovulation would start after cycle day 26 in a 31-day cycle, right? (Sorry, I don’t know much about how ovulation timing works.)

She is 15F teen. Yeah, I know I am really regretting it I can't be more sorry.

What are the chances of pregnancy in this situation?

Thanks in advance.
