Amateur- I’m freaking out! PLEASE HELP!!

This is absolutely lame, but someone please help me out!!

A couple weeks ago, I met my boyfriend after a really long time.. and things got a little out of hand..

He didn’t go in completely..it was painful for me so he didn’t force.. and there was no ejaculation near me.. but his penis was in contact with my vagina for a really long time, I’m absolutely worried about the pre cum.

I have never been intimate with anyone. I’m a virgin. This is the farthest I’ve gone with a guy till date.

I’m supposed to get my period today.. but there’s been only little brown discharge since last 2-3 hours. I have mild cramps and l backache but doesn’t hurt that bad. No sore breasts, no nausea.. just brown discharge which doesn’t happen very often. My periods are pretty much on time , always.

it’s becoming more and more stressful for me with every minute passing by.

AM I OVERREACTING?

I’ve been reading a lot of things on the internet and it’s freaking me out, y’all!!!

PS. I feel like this is really lame to even ask about this. But this is absolutely worrisome for me.
