Not sure if its wees or waters...

I'm not sure if I wet myself or my waters broke 😣 Today I've been leaking, only smallish amounts but it's when my bladder has been empty (or so I thought). My right leg has also been numb most of today so I don't know if it's just a pinched nerve making me lose control of my bladder. I'm not due for another four weeks. Should I ring my midwife? I don't want to bother her if I'm just wetting myself.
