Pelvic pain that gets worse with standing

Is anyone else having pelvic pain when they stand or walk? This is different than round ligament pain this directly from my pelvic and vaginal region. I don’t remember it with my daughter. I don’t know if it’s the pressure of baby when I’m standing? It’s very uncomfortable. It’s not taking my breath away or anything but yesterday I had to sit down and couldn’t finish vacuuming for awhile from it. I have an ultrasound on Tuesday and see my doctor on Friday but what do you think? I feel like maybe baby has been slightly less active too but he’s still moving.
