Sayang, keputihan tu memang normal during pregnancy, tapi kena check dengan doctor untuk confirm if it's GBS or just the usual hormonal changes, this is important especially since you mentioned the pessary (insert ubat) didn't help. Please don't worry, tapi jangan tunda untuk jump to your GP atau midwife sebab they need to swab and test properly, okay? A few of my mum friends had similar concerns and it cleared up after the right check, so go get that peace of mind!
