Pain and Pressure

I know this has been asked a lot, so I apologize in advance. I have had a rough time so far with this pregnancy. A lot of severe low abdominal pain and discomfort. My doctor has checked my cervix and everything seems okay so I've just been told to rest. The pain went away for about a week and it's back but slightly different. I now have intense pressure that's causing swelling. I also have a lot of vaginal muscle, pelvic and back pain. It comes and goes but is getting more intense. Anyone else experience this and have suggestions? I don't think I'm having contractions and I'm not bleeding. I'm being fitted for a support belt this week and have a call in to my doctor but I'm worried. Strange thing, when my little girl is active, it is worse. Thank you all!
