The abdominal cramping in early pregnancy is mainly considered to be a normal physiological phenomenon in early pregnancy, while the possibility of preterm miscarriage and ectopic pregnancy cannot be ruled out; farting is a normal physiological phenomenon in human body. If the patient has been diagnosed with early intrauterine pregnancy, the abdominal cramping in early pregnancy is mainly considered to be a physiological discomfort caused by pregnancy, which is a normal phenomenon due to early embryo implantation, uterine ligament pulling and hormonal level changes in the body leading to accelerated maternal metabolism. The discomfort is usually short term, intermittent lower abdominal discomfort, the degree of which is generally mild, obvious when bending over, squatting and other actions, and can be relieved after lying down and resting. At this time, we should pay attention to rest, avoid exertion, eat less spicy and sour food, and apply local heat if necessary; if the discomfort of abdominal cramping is prolonged and gradually aggravated, or accompanied by a little vaginal bleeding, we cannot exclude the possibility of preterm abortion, and we need to immediately go to the hospital to recheck blood HCG and early pregnancy ultrasound for clarification. If the patient has no clear intrauterine early pregnancy in the past (e.g. HCG positive, – the ultrasound can not see the intrauterine fetal sac, the doctor suggested to recheck after one week; or simply positive urine test paper), at this time, the lower abdominal cramping should be alert to the possibility of ectopic pregnancy, such as abdominal pain is severe, need to promptly go to the hospital for recheck; if the HCG value rises, the ultrasound can see a mass in one side of the fallopian tube, no fetal sac in the uterus, highly suspect ectopic pregnancy, need to be hospitalized conservative or If the HCG value rises and the ultrasound reveals a mass in one of the fallopian tubes and no fetal sac in the uterus, ectopic pregnancy is highly suspected and requires conservative or surgical treatment in hospital. The discomfort of lower abdominal cramping in ectopic pregnancy is often manifested as prolonged, persistent vague pain in one side of the lower abdomen, which may gradually become intense and even fainting. If the symptoms are not serious, it is generally considered as a physiological discomfort of pregnancy, which is not harmful to the embryo; if the symptoms worsen or are accompanied by vaginal bleeding and other symptoms, it is necessary to pay attention to it and consult a hospital as soon as possible.
