sciatica back pain treatment

Ask for a physiotherapist or chiropractor PLEASE?
I am 23 weeks pregnant. Exercise 3-4x week, and generally feel great! The only problem I am having a dull pain is occasionally right in the middle of my buttocks. But zero back pain. It is likely that this caused by sciatica or pain pelivic later? And what is the best treatment? Surely execising do I? Thanks for the help.
could be a reality. I saw a chiropractor for problems was having and helped me a lot. Until a professional advises you not to exercise, I want to continue with it. Good luck
