24 weeks, CONSTANT twitching?

Hey guys. For about 2 weeks or so now whenever I go to bed when baby is active (sometimes he’s asleep when I go to bed) I get unrelenting twitching sensations all in my stomach. I’m not sure if it’s my muscles, or baby. But it’s a nightly occurrence now and it’s so often and so strong it’s starting to prevent me from sleeping. It doesn’t hurt at all, and baby is still active as usual. It’s just incredibly annoying. I’ve been trying to sleep for a couple of hours now and it’s been happening on and off (mainly on) the entire time. Does anybody know what this is? :( it’s too fast and too strong to be hiccups. It feels like a phone vibrating, or like strong muscle spasms.
