It's kinda embarrassing

Ok so me and fiancé are trying to have baby, so we had sex on the 10th which was a day before my ovulation so we had high hopes for having a baby. Then today I was in the shower an realized that I had some cottage cheese looking discharge coming out of me it had no odor but a bit of itching from there I knew I had a yeast infection. So I went straight to Walmart and got yeast infection creams an everything I have to apply the cream for 7 days. Though it says nothing on warning label that says it affects you while trying to conceive, does this lower my chance of getting pregnant because I'm putting cream up there, I'm very concerned right now.......
