Need help/ Yeast infection

Okay so I think I have a yeast infection , I had one before and they are the same symptoms, they started today (itching, white thick discharge) and I'm currently 9 weeks pregnant should I call my OB to let her know my symptoms? I'm actually pretty scared to take anything since I'm still early on my pregnancy. Or should just wait 3 more weeks for my next appointment? And any at home remedies that are safe to relief the itching? Thanks in advance!
