In the early stages of pregnancy if there is a vague pain in the abdomen, you should first go to the hospital to check the gynecological ultrasound to see the development of the embryo. If the menstruation is usually more regular, usually around 40 days after menopause, you can see the gestational sac in the uterine cavity as well as the fetal heartbeat, as long as there is no indication of fluid accumulation in the uterine cavity, the abdominal pain is not aggravated, there is no vaginal bleeding, pay attention to rest, avoid overwork, and do a good prenatal checkup on a regular basis. If the abdominal pain worsens, go to the hospital immediately, because many people after pregnancy, there will be a uterine contraction pain not accompanied by vaginal bleeding, which are normal early pregnancy reaction, do not need special treatment. However, if an ultrasound is done and the ultrasound suggests that there is fluid in the uterine cavity or there is vaginal bleeding, etc., it is a sign of preeclampsia. If you intend to have a baby, you should give medication to preserve the pregnancy, and pay attention to rest and close follow-up.
