Does anyone drink apple cider vinegar in their water? I usually do a tsp in a glass of water to help with my sensitive stomach and bowel irregularities because it helps keep me regular. Do you know if it is safe to continue using during pregnancy?? I miss my apple cider vinegar and it really was helping my indigestion. Thanks!
