Really bad pains

Morgan
Every since Monday off and on I have been have really bad leg cramps, lower back pain and pelvic pain. I had a doc appointment Monday and he was already head down. Is it possible he is just moving down farther or should i inform my doc to make sure it's nothing serious? My next appointment is December 15th and I'll be 34 weeks and 3 days. Do you think she will start checking me then or at the next appointment
