Sayang, any discharge changes in pregnancy should really be checked with your doctor or midwife as soon as possible, better safe than sorry at 35 weeks okay! Only they can tell you properly what it is and if baby is fine. A few of us mum friends have been through similar scares, and honestly the peace of mind from a quick call to the clinic is worth it. Don't worry yourself too much, most of the time everything is okay, but let the experts confirm for you. Take care!
