Low down on my left side I've had a really irritating twitching in my tummy . It's not painful but it's driving me insane!! Thought it was trapped wind at first but it's been there for over 24hrs . I'm definitely not pregnant before you ask lol! This isn't something to do with endo is it? You can see it moving from the outside too ( nearly looks like a baby kicking ) I can feel it through the night too .
