I experience this every time I lay down. It's probably just the pressure from your baby squishing down on them. Makes your heart work harder to pump a good blood flow to. Whenever my baby girl moves in my belly it makes me heart beat fast and breath heavily.

Squishing down on organs and veins*
Thank you. It had been going on for week and a half. Just wanted to make sure everything was ok.
