This is definitely TMI for me but feel a bit embarrassed to ask what it could be. I'm 29 weeks pg and have always had a problem with both UTIs and thrush when pg. However I'm now having a watery/powdery discharge that smells quite musty or vinegary. I have spoken to midwife about it and she has done a swab and a urine sample but the tests won't be back for a couple of days. Any ideas??
