Pain in abdomen

This is my first posterior placenta, I didn't feel alot with my daughter. I am curious if anybody else has a consistent pain in the left side possibly from an elbow? This pain started like 2 days ago, started out happening when I ate. I don't think it's the actual eating though. Now it happens when I'm standing or eating. Kind of thinking that it might be him pushing against the same spot really hard. Plus his weight pulling. That's really what it feels like is pulling! But its in one side of my belly just under my ribs on the left side. (Not the right!) My daughter was IUGR so they stopped my pregnancy early & she was small. He is average to just above average. I guess I'm asking is this a normal pain? I'll mention it on Friday at my appointment but I've also been told that since I have consistent contractions at just under 32 weeks that I should be aware of everything & go to L&D asap if I feel off. I feel fine other than this consistent pain from what ever this is.
