Slight TMI? Pregnancy symptoms questions

So a few days ago I took 2 pregnancy tests, one had a faint line, but the other was a BFN. My boyfriend is convinced I'm pregnant, as is several of my friends. Anyways, I was wondering if (this might be TMI to some) an early pregnancy symptom is a very sensitive vagina? I've always had pain during sex (I have endometriosis), but the past few days have been different. I'm super sensitive during sex and even just barely being touched. Plus my nipples have been hurting like hell. I should get my period this Monday, but these normally aren't symptoms I have before my period.

So, lovely ladies, my main point of all this rambling was; is having an extremely sensitive vagina a symptom of early pregnancy?
