Smell

It could mean your ph was thrown off and could lead to a yeast infection or BV you should check with you OB just to make sure hope all goes well

Maybe the smell is from leaking pee? I change my underwear multiple times because I’m pregnant so I leak pee but I have no infections. You can wear a thin liner and change it and see if there’s a difference in the smell.

Pads are made from plastic so that will only harbor moisture, bacteria and any smells. If you’re peeing a lot that could mean your electrolytes are imbalanced so the water is passing right through you, rather than being soaked up and hydrating you. A liquid probiotic could do you some good, ginger tea too. If it starts to itch and bother you it could be BV or Yeast infection, either of which I’d recommend tea tree oil suppositories

Your ph balance could be off. Try drink lots of cranberry juice. If you have hair down there, It’s also possible that since your peeing so much the pee is getting trapped in the hair. But if your really concerned make a gyn appointment for the root cause and some tips to avoid it etc

That sounds like discharge and if there’s an abnormal smell it’s probably an infection. You should schedule an appointment with your OB/GYN so they can test you for any vaginal infection. In the meantime, just wash with warm water — no soap. When you go to pee, again just wipe down with some warm water and pat dry with toilet paper. Even hand fan the area so the area is as dry as possible. If you wanna use liners, pads or tampons, I suggest getting the cotton ones.
