I'm 30w2d and today my discharge is very different than it was yesterday. It's clear instead of the yellow-tinge that I've been having, and it seems to no longer smell at all, which I also found strange. I've felt extra "leaking" a few times when standing up. Baby has been moving much more than normal and I'm also experiencing back cramps and pelvic cramps that are low (like below my belly). My doula says it's likely nothing, but I can't help but worry. Any advice?
