Twitches/Spasms on left side of belly

S

Hi ladies! I’m 20 weeks pregnant today and for the last 1 or so days I’ve been getting this twitching/spasms on my left side in particular. It goes on for a few seconds and then stops and then might start up again right away or will happen again after an hour or so. Of course now I’m paranoid something is wrong. When I miscarried last time...at around 8 weeks I remember feeling my uterus twitch but I’m sure it’s not that. 🙏🏽. Any ideas? Is it the baby constantly hitting the same area and my muscle spasming? I really hope it’s not the baby himself that’s twitching like that. Would love y’all experience if your going through or have felt similar. Thanks!
