Watery discharge

Sorry TMI - I’m almost 39 weeks and so far my discharge has been 100% white/creamy... now all today it’s been completely watery, water based, no consistency or colour whatsoever. It also smells of nothing (hubby checked too)... I’m worried it might be a slow leak! Has anyone had a similar experience?

EDIT: just thought I’d update that the following day I had passed a huge chunk of my mucus plug. Hopefully all others are positive signs that things are happening as I really don’t want to go overdue and be artificially induced.
