Am I okay?

So to make this short and sweet, my period started on the 1st -5th of this month and then my period/ spotting started on the 19th - today (currently 7 days) and I’m super worried. My period has been normally brown and light but this one it’s weird. My period/spotting is very thick brown. Like it looks thicker than normal.

Im on birth control since 2020, 7 months ago I started taking my pill religiously with only 30 minute wiggle room if I can’t take it exactly on the hour. My pill is a combination pill and I take active pills for 3 weeks and then take no pills during my “period” week and then start another pack after the period week is over.

I also took an antibiotic for 7 days during my period in the beginning of the month for a cyst I have

Im still a virgin but im also freaking out that I might be pregnant. So the situation is on the 8th this month. I made my boyfriend ejaculate (oral) and he wiped his hands with a rag and then helped me with my shirt and sweater and then my underwear. Im freaking out over the possibility that his hands were still moist ( he claims it was dry but ofc I still freak out) and that maybe sperm transferred onto my underwear and now im possibly pregnant. Yeah I know, it would be a miracle if I was pregnant but im so afraid of the possibility. I know im not pregnant but I still look for signs and I spook myself out. I stress myself out to where I need to calm down and breathe,

My question is, am I okay? Or is something not right? Im worried that it could be implantation bleeding even though it’s been more than 3 days my period began. But I’m also worried that I could be pregnant.

Btw I was also very sick on the 13th and took a lot of cold medicines. Not sure if it was the flu or a cold but I’m still coughing till this day (tested negative for Covid,)

What do you think? Could it just be stress and that’s it? That cause my period to come early and to last longer than normal even on the pill?
