Well..my OB told me to watch out for this because sometimes the waters don't just gush out in one big puddle, but leak in a slower fashion. I would advise you getting that checked out asap.
Incidentally, they also told me that if you are unsure if it is urine or amniotic fluid to sniff it (lovely image there, lol) and if it smells sweet it is amniotic fluid, otherwise it will probably smell like wee...lol.
Hoping you get to meet baby soon. I think it sounds like you are about a week further on than me.
Hope that helps a little.
