30 weeks pregnant. So uncomfortable. Wondering if this specific discomfort is relatable

I consider myself really lucky to work remotely, with a very flexible job that involves sitting at a desk.

Sitting, in itself, becomes painful after an hour. Twin B is located really high up, geographically right by my breastbone I think? When I sit for awhile it feels like there a large stick stabbing me upwards.

I’m a telehealth therapist, in between sessions i try to walk around a bit to ease the discomfort. But I can’t get up during a session obviously when it might become really painful.

Do other people experience this? Pain just sitting? It feels too early to start maternity leave.
