The feeling of wanting to poop in the early stages of pregnancy is generally considered abnormal because it represents a significant pelvic fluid accumulation, so it can often be caused by pelvic inflammatory disease or ectopic pregnancy. In the early stages of pregnancy, the uterus is not significantly enlarged, so the feeling of wanting to poop is not caused by the enlargement of the uterus pressing on the rectum. If there is an obvious urge to poop and pain in the lower abdomen, it usually means that the amount of fluid in the pelvic cavity is high, and the stimulation and pressure of the fluid will cause the obvious pooping symptoms. When a woman is pregnant with an ectopic pregnancy, due to the local narrowing of the fallopian tube, the ectopic pregnancy mass will rupture and cause a significant amount of fluid, which will flow into the pelvic cavity and press on the rectum, causing a feeling of swelling that makes her want to poop. Therefore, when women experience this feeling, it is best to go to the gynecological department for an ultrasound and, if necessary, a double examination to confirm the specific cause.
