Yeast Infection

The opening of my vagina has been itching the past couple of days. Currently pregnant and I know yeast infections are super common during pregnancy, I’ve already had one at 13 weeks, used monostat per doctors orders and it cleared up. The thing is i accidentally threw away the cream for the outside. Do you think I’m getting another? I’m 25 weeks now. There isn’t any yeast or symptoms (other than itching) like last time that I’ve noticed. We just moved and i don’t have a doctor here yet in order to ask if I should pick up some monistat again.
