Round ligament pain

What does this feel like? I had an ultrasound two days ago and she had to press really hard, trying to get the baby to move. After 15 minutes of trying to turn the baby, she did an internal ultrasound. 
Now two days later, right under my stomach, near the pubic area, is so sore! It's like I worked out and pulled a muscle. I really notice it when I am using the bathroom, cause we use that muscle to
pee, and when I am walking a lot. I still feel it when I am laying down or even sitting.
Any advice?
