I have had yellow discharge throughout and apparently normal as long as it's not smelly or itchy. To be fair I am 21 weeks tomorrow and it's changed to being clear now but when it's thick, every other day or so, it's still yellowy. I am being less stringent with my Pregnacare vitamin taking and not overly worrying if I forget for a day and that has made it clearer in colour. I think the vitamins, particularly Pregnacare can make everything, including urine really luminous yellow! Xxx
