Menstrual blood in mouth. Hiv/Hep C???

Dear Dr,
Last month I had oral sex with a woman and didnt realized she was at the end of her menstrual cycle. After we finished, I noticed there was blood on the condom. My concern is, since there was blood on the condom I most likely got it in my mouth when I went down on her. Recently, I found out she has Hep C and now im concern if she has HIV as well...
1) What are my chances of getting either one?
2) Its only been 4 weeks and I just had a blood test done just waiting for the results, will the results be conclusive or should I have it done in 8 weeks again?
3) Ive read that Hep C can stay dormant for years and not have any symptoms. It mentions in order to determine if you have Hep C you would have to wait until symptoms begin or after you get symptoms Does this means if theres no symptoms if could still show up in 5-10 years from now? Or will I be in the clear after 6 months if blood test is negative?

Welcome to the STD forum.

Question 1)

First, you have the common misconception about sexual transmission of hepatitis C virus (HCV).  It is not an STD; the only situation in which sexual transmission has been shown to be a signficant risk is among gay men with particularly traumatic rectal sexual practices, with bleeding.  Also, HCV is not known to be transmitted by oral contact with blood.  I can't tell you there is no risk from the exposure you describe, but certainly it was very low.

As for HIV, that's also zero risk for practical purposes.  If your partner had HIV, she would have told you.  (Why would she tell you of HCV and not also tell you of HIV?  And you can be 100% sure that if she is known to have HCV, her doctors have tested her for HIV.)  And even if she had HIV, the chance of transmission by oral contact with menstrual blood probably is very low.  HIV is not easily acquired by oral contact of any kind.

2) 4 weeks was too soon.  Have another HIV test at 6-8 weeks.  I'm not sure about HCV test timing but I believe 6-8 weeks also is fine.

3) You read wrong.  The blood test is accurate for judging HCV infection, with or without symptoms.  If your blood test is negative, you don't need to worry about it any futher.
