Is it normal to have lower abdominal cramps at 30 days pregnant?

Patient's question:

Symptom Description: Occasional abdominal cramps at 30 days of pregnancy
Past Treatment and Effect: Worried about ectopic pregnancy, did an ultrasound, which was normal
Expected Help: Is it normal to have cramps?

Doctor's answer:

Note that abdominal pain in women during the early stages of pregnancy is also a normal symptom. However, if your description is of intermittent cramping pain, it is recommended to visit the obstetrics department of a hospital for examination. Based on the situation you described, it is highly likely that the pregnancy is accompanied by adnexitis, but ectopic pregnancy cannot be ruled out either. Further tests should be conducted, including dynamic monitoring of blood hCG and a subsequent ultrasound examination.
According to the situation you described, I suggest you continue to pay attention to rest, as the pain may be caused by the stretching of the enlarged uterus after pregnancy. In this case, a follow-up ultrasound examination of the uterine adnexa is recommended after one week.
