Possible yeast infection

So I had sex October 30th , haven’t had sex since then . For a week now I’ve been having discomfort . We used a condom when we had sex . This friction was kind of rough . I was fine , but now it’s like white stuff coming out and discomfort . I don’t know if it’s from me using ivory soap or from the sex . I never had this problem with my vagina . Is it the sex or soap?
