Left sided pressure

I have been having pressure on my lower left abdomen below my pelvic bone since last night. Has anyone else experienced this? I’m 8 weeks today. We saw our baby a week ago and heard the heartbeat so I know it’s not ectopic. It’s not painful just annoying pressure. If I put pressure on it, the pressure goes away. I’ve had this sensation before I was pregnant and was always told it was nothing or I had a small cyst. If this was a cyst I think they would have seen it last week when I received transvaginal ultrasound? Ugh.
