My gf is quite irregular with her period, and she has Hep c. Should I be more worried? Or should I approach this the same way as every other lesbian that asked you a similar question? Not sharing toothbrushes, razors, etc.

On another note

My gf had sex with her ex-bf on Jan 10th. That same night we had sex. She didn't mention it until Jan 30th. And I was supposed to get my period Feb 1st. I've been late for 5 days now. A friend of mine mentioned the weird possibility that I might be pregnant.

I was just wondering, is that even remotely possible?

I find it rather hard to believe, but the way my friend explained how if the semen came in contact with her vagina, and then touched herself for some reason or another, then fingered me...it all scared me a little bit because I can't quite recall how everything went down that night. My gf says I'm late because I'm too worried about being late.

Thank you in advance.

I would not attribute a late period to hepatitis C. I also do not suspect pregnancy based on your history.
