cm help

For the past three days I have woken up at had very very VERY watery CM. it feels as if i have peed myself, TMI but sometimes it runs down my legs as i get up to go to the bathroom. then thru the rest of the day its fairly dry sometimes watery but not like how it is when i wake up. I am 4-5 DPO. last night my cervix felt very high, soft and closed (not sure if that matters here. but what could this very watery cm be from?? i’ve never had it like this before!!
