Pain in pelvic area 14 weeks normal?

This is my second pregnancy I had this pain later on with my first but am also growing much bigger with the second. It is on the left & right about an inch above where the thigh meets your torso. Has anyone else have this? It happens when I have been very active bend over a bunch during the day or stretch to reach something. It is very painful it feels like pulling a muscle similar pain. Any advice would be great as my doctor said it was normal to have pain there due to all the increased growth & increased blood flow & sensitivity etc. But I would really like to hear from some other moms as it is making me a little nervous.
