Am I feeling Little Foot or no? I'm at work and I keep getting this pressure-y, somewhat crampy, hard feeling in my left side. I touch it and it's extremely firm, moreso than my right.

I haven't really felt flutters or the popcorn feeling, so idk what I'm feeling. All I know is it distracts me sometimes
