Are my boobs okay?

So my currently my nipples seem to be sensitive? I can’t tell if it’s sore or not but right now they are sensitive and any fabric or something touching them makes them itch. (My right nipple is the one that’s itching/irritated more). I’m wondering if this could just be a PMS symptom. I’m at the end of my birth control (norethindrone acetate and ethinyl estradiol) and today is my last day of taking the pill and then starts my week of no pill (for period).

I’m only wondering if something else is going on because I am a virgin (I’ve never had a penis inside or near me) but my boyfriend did ejaculate and cleaned it up with a rag, washed hands with water and soap (it’s a public bathroom so idk if the soap is 100%) and then 10-15 minutes later he fingered me. I know if there’s any possibilities it would be RARE if I’m pregnant but it still worries me. I have been taking the pill on time every day but the day before my boyfriend fingered me- I took it around 40 minutes late.

I’m I just worried for no reason and I’m okay? Plus my boobs do look a bit bigger-
