Reduced movement at 20 weeks

This is going to sound really paranoid because I’m only 20 weeks but hear me out. The last 2 weeks I’ve felt regular and strong kicks/movement any time I ate or sat down. The last few days I feel like I exerted myself more than I would like to because I’m moving. It’s going on 3 days now that I feel just a light tap a few times throughout the day.

I’m traveling this weekend to see family so I won’t be home but yes Monday I have a regular OB appointment where I assume they’ll use Doppler anyway and I’ll express this concern!

I’m just wondering if anyone else has experienced this, what was the outcome and do you think it’s because of my over exertion? I was carrying some light things up and down the stairs but I didnt hurt myself. I was just really tired and my legs hurt. 💖💖
