Abdominal pain in early pregnancy like menstruation is mainly considered as normal pregnancy reaction, but it may also be related to abnormal conditions such as pre-eclampsia, ectopic pregnancy, etc. You can go to the hospital for obstetrics and gynecology examination to determine the causes and conditions, and then carry out causal treatment. The main reasons and treatment 1, normal pregnancy reaction: slight abdominal pain in early pregnancy, similar to the pain of menstruation, is due to the increase in secretion of estrogen and progesterone during pregnancy, which promotes embryo implantation and the gradual increase in the size of the uterus, causing tension in the abdominal muscles and ligaments and causing pain. It is a normal pregnancy reaction and does not require special treatment. Try to relax and rest in bed; 2. Pre-eclampsia: If there is paroxysmal pain in the lower abdomen, like menstruation, accompanied by a small amount of vaginal bleeding, it may indicate pre-eclampsia. It is recommended to consult a doctor promptly and perform abdominal ultrasound, blood HCG, progesterone and other related examinations to make a clear diagnosis. Under the guidance of the doctor, treatment of fetus preservation can be carried out, intercourse is prohibited, pay attention to rest, maintain a relaxed mood and strict bed rest if necessary; 3. Ectopic pregnancy: if there is paroxysmal pain in the lower abdomen, like menstruation, and vaginal bleeding gradually increases, ultrasound examination indicates that no intrauterine gestational sac is seen and the fetal sac is visible outside the uterus, conservative treatment or surgical treatment is required at the doctor’s discretion. Precautions should be taken to avoid sexual intercourse in the early stage of pregnancy, take appropriate folic acid supplements to prevent fetal malformation, and keep a happy mood at the same time. Eat more nutritious, high-protein foods, such as fish, shrimp, eggs, milk, etc. You can also take appropriate relaxing and soothing outdoor activities.
