Hard Stomach and Pregnancy â What are the Causes? Here are some of the causes for hard stomach during pregnancy: 1  Hardening of the abdomen during the 21st week is quite common because the growing uterus applies immense pressure on the stomach walls, which in turn results in a feeling of hardiness.
Your uterus contracts, causing your stomach to harden. You'll feel the cramping come first and then slowly (if it is a real contraction not BH) your stomach will get hard and stay hard throughout the contraction (45-60) seconds or so. Source(s): Mother of 3 and 35 weeks with #4.
