upset stomach

Amy
Hope you ladies can shine a light on what I should do... for the past 5 days this being 5th I have woke up to a very sore stomach and need to run to the bathroom every time I eat. Iam worried if it's a bug it's harmful to the baby. Iam 21.5 weeks, should I call a midwife? It's effecting how I fell her move because all I feel is stomach cramps. It's consistent throughout the day.
