FEEL LIKE IM PEEING MYSELF

I am 19 weeks, 3 days & for the past couple days I’ve had this issue with my discharge... I’ll be sitting there & out of nowhere I’ll feel a little gush of liquid & I’ll run to the bathroom thinking I just pee’d myself or worse (blood), but then I come to realize its just discharge. My underwear won’t stay dry :/ it doesn’t smell odd or look odd it’s just really watery. Is this normal, have any of you ever had this before?
