I just recently started taking Xenadrine EFX (Ephedrine free) because a co-worker told me that with diet and exercise it really works. I also just recently started experiencing pregnancy symptoms, and I've heard that Xenadrine can cause miscarriages. I'm just wondering if it's safe, and if I am pregnant, if it's a risk to the baby. Also, if it causes miscarriages, can it cause long-term problems with conception, pregnancy, or delivery. Please help!
