Leaking breast at Week 27 (clear discharge). Is it normal?

Hi mummies, #1sttimemom here. I’m currently at 27 weeks pregnant and today I noticed my left breast started leaking leaving some stains on my top. It was hurting a little for the past few days but not anymore. Couldn’t tell if it’s whitish but it seemed clear and doesn’t have a smell. Just want to know if this is normal and any advice? #pregnancy
