I think I had a yeast infection, and let it go too far untreated. Can it be treated with regular store remedies?

I had the yeast infection for the first time. I used Monistat 7 and i felt fine. Well the day after the last day of treatment, my fiance and I thought it was fine to have sex. So we did. The next morning i felt the symptoms of the infection. I bought the Monistat 1 just in case but can anyone answer why it came back or if im allergic to the lube on the condom?

is there any good site to buy Yeast Infection cure guide??

I have a yeast infection, so I bought a yeast infection cream. Can it reduce the effectiveness of the pills?

I just got my pills to insert for my infection but i had sex earlier today. I was wondering should i still start the medication, because my doctor said not to have sex for 6 days. I think she meant not to have sex if i already started the treatment because it is for 6 days but am not really sure. Should i start it tonight or tomorrow night?
Oh yea and can my partner get it. it was unprotected sex because am pregnant.
