muscle pain with second pregnancy (after c section)


I had my first baby via c section 2 years ago and am now 30 weeks pregnant. I am having crazy muscle pain mostly on my lower right side and horizontally across my pelvic area, a little lower than the round ligaments. My muscles just feel like they're being torn apart. I have an appointment with my doctor next week and of course I will discuss it then I just thought maybe this is a normal pain for second pregnancies after healing from a c section. Has anyone felt this? It hurts the most when I am laying on my side(either side) and move my knee up in the air like I'm doing a leg lift.
