Normal or abnormal... Discharge

Ever since I've been pregnant... I'm now 22 weeks, I've had increased discharge (which I know is normal). My discharge is usually clear to creamy white and I've never had a yeast infection before so I don't know if this is yeast or not. I have no pain during urination, or sex and no burning or itching at all.... I'm sure it's normal but I guess I just worry... And my next appointment isn't for a couple weeks.... I've read a yeast infection won't hurt the baby but I always think they maybe it's something else... I don't know lol
