@rhea.16, I went through this with both of mine. it's more than likely pee from were the baby's head is pressing down on your bladder. I would go through 3 to 4 pairs of underwear a day the last trimester.
well it's just kinda damp. its not pee because I can feel it come out and that's not where its coming from. My nose has also been stuffy for two months so I probably just can't smell it lol
