Yellowish/brownish/greenish discharge

Anyone na nagkaron na ng ganitong discharge? Tapos may super light pain sa puson. I know it could not be normal and I have to see my OB soon pero it's 10pm and ayoko na istorbohin si OB and I think din naman sya emergency para magpa ER na? Baka lang po may nagkaganito na din sainyo? Please ano sabi ng OB nyo? And ano ginawa nyo? No smell naman, hindi rin sya parang sipon. 21 wks pregnant. #pregnant #discharge Thank you!
