Chiropractor during pregnancy??

Just wondering if any of you pregnant ladies or moms went to one during pregnancy and what your experience was like and if you would reccommend it. I am very small framed and carrying twins which is causing normal back pain to begin with however in October I did something to my back at work think it would heal and be fine and the pain had came back periodically and right before I was going to get it checked out I found out I was expecting. I have been thinking of seeing a chiropractor and received a good referral but I have also heard horror stories from people in the past so just looking for opinions.
