i dont know what to do...

im 33 weeks and for the last week i've been having some weird symptoms. my eyes have gotten blurry 3 or 4 times, i've had excessive gas(some times painful, some times not), i have extreme back pain, im overly tired (not just pregnancy tired, but wiped out), i have a pain in my upper leg that doesnt seem to go away, and im having pressure from my lower belly down to my private area (not painful, just very uncomfortable). i dont know if i should call my doctor, or just wait until my appointment on wednesday and mention it. i dont want to ignore something serious, but i dont want to over react. not sure what to do?
