Just wondered if anyone else has experienced this. It's only happened twice to me, where I've woken up early morning - like 4am ish - needing the loo. Doesn't feel like a panic attack or anything because I'm not waking up flustered, shaking or out of breath. It doesn't even feel like my heartbeat either but when it has happened, I've been really really relaxed and half-asleep. Could it be baby's heartbeat or hiccups even? xx
