Pregnant women can often suffer from constipation due to hormonal effects and fetal growth. Normally, a pregnant woman cannot have a bowel movement for more than 2-3 days. If it is more than 3 days, and the stool is very dry and strenuous and takes a long time to pass, then constipation occurs. If you have a bowel movement once every 2-3 days, it is normal to have a bowel movement with no effort. If you had a bowel movement once a day when you were not pregnant, but after pregnancy, you have a bowel movement for 2-3 days and it is very difficult to pass stool, you are constipated. At this time, it is recommended that pregnant women should ensure good bowel habits, pay attention to good dietary management, eat more green leafy vegetables and fruits containing more fiber, and take appropriate physical exercise to promote gastrointestinal peristalsis, and ensure appropriate drinking of water to lubricate the intestinal tract, so it is normal for pregnant women to have a bowel movement once every 2-3 days.
