Is really brown watery discharge normal at 35 weeks?

Well i really need help as to why i have a really brown to almost orange tinge color in my underwear when i awoke i was soaked i thought it was just increased fluids or urine as they say its possible but ive also heard its ok if the color is as described as long as it is not red blood. I have had 2 bubs so i know the hole shabang went early with both bubs lost mucus plug had water break in labor not before it started. I have also noticed since this orange red/brown tinge in my underwear that i have been getting really painful pinching sensations in my vagina around were my cervix would be it can become painful and if i get them when i walk it stops me in my tacks could all this just be a sign of dilation. or could my hind waters have broke as i have been getting soaked since tuesday and today is friday.
