Yeast infection suck while pregnant

I notice with third pregnancy I get more yeast infection I only had one with second baby n first pregnancy as well. I called ob she said use Monistat cream til next ob appointment if prescription needed she will but suggests no sex for rest of pregnancy does that cream help? Were certain pregnancies make u get more yesst infection then previous ones I never got yesst infection when jm nkt pregnant so it's been so annoying any other suggestions to use or drink but definitely going have hubby get me cream tonight or tomorrow
