Sore nipples at 13dpo? AF or PG?

Janelle

*Disclaimer* I had unprotected sex 2 days after I ovulated, just wanna make that known to show help you ladies weigh out the circumstances 🙃 lol

ANYWHO, this whole 2ww I've been nervous as f' cause I'm not ttc at all but along with my normal pulsating/throbbing sensation that I get 2-3 days before AF & my super sore boobs something new happened this month. Now that it's 12AM, AF is technically due today but speaking on terms of "earlier today (13 dpo) one of my nipples has been stinging severely on & off. One time they both stung together but for the most part, it's just been one of them and it literally feels like it is ON FIRE! I have never in my whole 22 years of life experienced any type of sensation to my nipples during a hormonal period. Is this a common AF symptom or could I be showing signs of early pregnancy? Although I'm not ttc, if AF doesn't show up later on and I wind up being preggers, I wouldn't be mad at all ☺️ it would just be very unexpected. And if this means anything, I usually always get sore boobs during pms so I've built up a pretty strong tolerance to them but this month they have been unbearable. Like ridiculously sore.
