You might have a yeast infection or bv.
I know it's not an infection, I've had those. Plus, I've heard odor is common in pregnancies.
I kno I be having that too now that I'm pregnant n I just got out the hospital n I don't have nothing
There isn't a lot you can do about it. You can't use vaginal wash. Just make sure you shower regular and wear panties
You can wear panty liners and also use flushable wipes when going to bathroom. It keeps my odor down and leaves me fresh.
