Yeast infection

I just found out on Thanksgiving that I’m pregnant at 10dpo. I was on Augmentin antibiotic for a sinus infection for 10days and now am noticing I have a yeast infection. I bought a box of vaginal cream 3day medication but am wondering if it’s safe to use? I consulted my Mayo Clinic guide to a healthy pregnancy book and it said it’s fine but to consult your ob. Well it’s the weekend and I don’t know what to do.... thoughts please!
