If you completed the course of candid
V3 then your infection is treated .Having sex after that will not affect you or your partner ;only thing is the male partner is said to be the carrier of candid infection so when you get treated it is always advisable to get your partner also treated with oral antifungal
to avoid recurrent infection.It is just a possibility but as such it will not harm both of you.As for pregnancy
it is not related to candid v3and if you have unprotected sex during fertile period that is ovulation time then you can get pregnant.
