TMI but..

Hey ladies this is my 4th pregnancy and I only have 1 still with me but I had him about 4 1/2 years ago and I don’t remember quite everything...

one thing in particular

When I’m up and moving around I feel really heavy discharge and when I go to the bathroom and wipe it’s like a weird clear/ orange color it doesn’t smell or anything and my pee is super dark it kinda scares me because I drink like a 24 pack of water in 3 days.

So basically is this normal or should I call the doc??

I’m 21 weeks btw!
