It is common to get an infection during pregnancy so don't feel bad or anything. I've probably had like 4 or 5 reaccuring yeast infections when I never had them until I got pregnant. You'll find a lot of things happening to your body that didn't happen before I've had rashes, breakouts, allegies ect.
infection go get checked hun. As Dcat stated not all infections have smells but if you think about it not everyone gets or has the same symptoms
Its an infection of sone kind...not all infections have a smell so go get checked asap.
