Talk to Gynecologist on IBS And Lactose Intolerance

I have IBS and lactose intolerance and dr gave me digestive enzymes that irradiated the symptoms to a great degree. But now I'm pregnant and have stopped taking the enzymes. I'm in the start of my second trimester and have started to have the IBS symptoms again. Please let me know if it's safe to take digestive enzymes during pregnancy or not? If not then please tell me any other method to relieve the symptoms.
