Pelvic/low back pain

Ugh, so i don't want to complain...but i hurt...i've had an ongoing (7 years now) issue. I have pain in my lower right pelvic area and around my low back, sometimes it radiates down my legs....i've worked for a chiropractor for over 10 years so i know its not a spinal/nerve or muscle issue. Ive had a colonoscopy, laporoscopy of the abdomen, countless ultrasounds...they have found nothing. No endo which my dr thought for 6 years, very small ovarian cysts, not enough to cause the pain...im 5 weeks pregnant and am worried something is going to go wrong with the baby. The pain is unbearable at times...any thoughts??
