TMI vagina question

I'm a little embarrassed about this but I have to know.

Normally I take my showers every 3rd day, 2'nd day depending on what I did. I don't take one everyday because my skin just dries out really bad. But being pregnant and with my vagina producing more discharge I'm starting to find I'm gonna have to start taking one every day because of the smell. I know for sure it's not a yeast infection because there's no irritation, itchiness or that weird white/yellowish discharge.

Could it be the panties I'm wearing too? Does anyone else find this is happening to them? It's kind of gross for me.
