Ligament pain?

Hi ladies, so I'm having constant pain that feels like a pulled muscle at the top of my stomach. I'm not a first time mom (pregnant with baby number 3) but I don't remember feeling this, especially at only 9 weeks and 3 days. I called my OB but the doctor wasn't in and they haven't heard back from him. I'm also having some back pain. I don't know if they're linked since I've had back pain basically this whole time. Any thoughts?
