Quick Question From Ppl That Experience The Same Problem ONLY

I Always Wear A Panty Liner But After I Turned 38 Weeks Ive Been Smelling Ammonia Down There 🙄 Does That Mean My Bladder Is Not Strong Enough To Hold Pee Or What's Going On ? I Don't See My OBGYN Until The End Of This Week I Was Just A Little Curious Because I Wash Well Etc
