Long story short, on New Years I gave my girlfriend oral sex, I have a canker sore (I know its not herpes) at the time, but didn't think anything of it. We also rubbed genitals, but there was no penetration at all.
Now, I come here to ask what may be wrong, she's about two weeks late on her period and said she's had an itchy burning sensation on occasion. She's been fairly worried about getting pregnant from the genital rubbing, and then remembered that I had a canker sore, and its come to this. She lives a good distance away, so I am unable to see this for myself.
What should she be watching for, or looking at? Could anything have come from my canker sore? Or can this all be explained with a lot of stress?
