Is Garcinia Cambogia Causing Lower Abdominal Pain?

Being that I am not now on any particular diet and I don't want to regain all the weight I lost, I have been taking garcinia casmbogia supplements. For the past three days I have had pains in my lower abdomen. That is highly unusual for me. I sometimes have upper GI problems but lower GI seems to function better. When I do have lower GI problems, it never seems to involve abdominal pain.
I will d/c the garcinia cambogia until further notice.
