Recurring yeast infection

Any mummies here experience frequent yeast infection during pregnancy? I am only at week 21 but already had it 3 times since I got pregnant. Gynae prescribed me with antifungal pessary during my last appointment, it did clear up for about a week and then it came back. The itch is bothering me a lot. Should I see a GP or visit other specialist clinic for now? My next gynae appointment is still 3 weeks away. #advicepls
