Less movement at 34 weeks

Currently driving myself crazy trying to figure out if this is normal or not.

I’m a FTM and since hitting 34 weeks I’m feeling less movement/less kicks from the baby. Google says this is normal because there’s not much room for the baby to move and I wanted to ask if someone had a similar experience?

I have a anterior placenta and quite small (5’3 and started my pregnancy at 104 lbs but gained a healthy 29 lbs so far) and my OB told me you can feel less movement when this is the case since I wasn’t feeling much up until 24 weeks. But after hitting 24 weeks I could pretty much feel the baby a number of times per hour.

Should I be concerned and call my OB office today or am I just overreacting?
