Feeling “spasms” in my lower stomach.

Well today I was sitting on my couch minding my own business... and I started to feel little twitches, you know like the first time you ever felt flutters??? In my lower abdomen, I still haven’t had a period, my son is ebf. I’ll be taking a test tomorrow, but is it possible I’m just having muscle spasms 😓 kinda freaking out.
