pls help :( - possibly tmi!

hi guys, i’m 19, im not on birth control or anything, and i’ve never had penetrative sex but the last time i did something sexual was on october 27th with my bf (for context, i gave him head, he came in my mouth, we made out and he gave me head later). it turns out that this was the day i ovulated. i’d like to think that i got my period on november 11th but i’m scared bc it was only 4 days long instead of the usual 5 or 6, and also it was rly thick, pretty stringy and clotty but most of the time, it never rly showed up on my pad but i’d see a normal amount of it on toilet paper. i haven’t done anything sexual since my last “period” (at least, im hoping that it’s my period 😭), but i’ve been showing symptoms of pms for about a week or so (bloating, sore boobs, headaches, etc but NO nausea or darker nipples). my next period isn’t due for another 4 days (december 5th), but i’m taking a test tmr anyway just to be sure, and i’m majorly freaking out anyways LOL. anyone have any input? pls pls pls help im super scared :((

update: i was being dumb, i started my period today LOL
