Is this normal ?

I’m 26 weeks today but the past few days I have had really watery yellow tinted discharge, so watery it soaks my underwear and I have to wear a liner. It’s especially when I first wake up but is maintained as I use the bathroom and wipe throughout the day. It’s odourless and not itchy. There was a day I thought I lost a piece of my mucus plug before but I figured I would know if it was or not considering this is my second pregnancy and I knew when I lost my last one. What should I do?
