Bruised feeling in labia/vulva early sign of pregnancy?

[Sanne]

I've been TTC for 4 months (now in the 2ww of the 4th attempt, I'm 12 DPO and had a BFN this morning). I have been feeling a bit tired and nauseous on and off, but have had that during the 2ww at some of my previous cycles as well. I even had a metal mouth for a week between O and AF one cycle, but not this month. All I have this month are the light nausea and tiredness, but I have a NEW thing I'd like to ask your opinion about: could a bruised feeling of the labia/vulva be an early sign of pregnancy? I have never had this before and I have not done anything (cycling, rough BD) to cause this light sense of pain. They feel bruised/swollen but aren't in fact bruised or swollen when I check with a mirror.
