Help!!! 40+4 what could this be??

Jade

So this morning I woke up and my pyjamas were wet and there was a wet patch on the bed.. I didnt think much of it put it down to having sex last night, maybe I wet myself a little I don't know but since I wasnt having pains I didnt worry.. I put a pad on though just to monitor it..

now I'm still leaking a watery subatance but it has a hint of blood in it. Should I be worried. I'm a first time mum so not sure what to expect 😕
