I think I pulled my right round ligament 😵 33 weeks

Yesterday earlier in the morning I was reaching for something on the floor while still in bed bc I was too lazy to get up and get it (🤦🏽‍♀️) and felt a very sharp pain in my inner right hip next to my vagina and just took it as I stretched out my round ligament little too much. Had an ultrasound later that day and had to have an uncomfortably full bladder, and the ultrasound ended up lasting over an hour and a half (paid for a 4D ultrasound, said it would only last 15 min). And it started hurting pretty bad in that spot again bc I guess my uterus was pulling on the ligament again from being so full. Baby’s face is also turned to the right with her hand by her face so it could also be from that, but it went away after a while after I peed. It’s 3 am now and I woke up bc I had a bad dream and then I noticed the pain again! I was laying on my right side and just had the worst pain in the same spot.

I have a dr appt on Thursday so I can of course ask her then but man i woke up scared that it was appendicitis! But then I learned the appendix is a lot higher up when you are very pregnant lol.

But has anyone experienced this? How do I manage the pain?! It hurts so bad!
