Hi, if you don't feel safe of that cream then probably it's better that you don't use it first. I had the same problem and my gynae prescribed a cream to use externally not inside of the vagina. On top of that there is a pill that can be insert into your vagina to clear the fungus, you can ask your gynae about it. I had the pill inserted every two weeks from my second trimester until the end of my pregnancy because mine was quite badly infected.
