My discharge changed to something like what you're describing at about 36 weeks this time. It's pretty normal...you get an increase in discharge towards the end. Fun, huh? I take 2-3 showers a day, just to freshen up and make sure I don't go getting rashy down there or anything from the extra moisture. You can wear panty liners, but they're notorious for breeding thrush if you wear them for extended periods.
