For the past week or so I've been getting bright yellow discharge in my underwear. Every time I change my sanitary pad it comes back. Is this another normal pregnancy symptom or should I worry? It's odourless and doesn't itch etc. I'm 37+5 weeks pregnant. I know amniotic fluid is supposed to be colourless so don't think it's that but I'm a FTM so have no idea. Don't want to ring doctors if I'm just peeing myself if it's normal!

Tia!
