Pregnant for five and a half months, sometimes the lower abdomen feels hard but there is no pain, what could be the reason?

Patient's question:

No

Doctor's answer:

Hello, according to your description, an ultrasound can be done. Generally, there shouldn't be any major issues. Pay attention to prenatal care and daily care, it's good to supplement trace elements appropriately, and it's good to have regular prenatal check-ups. Pay attention to a healthy diet, and avoid harmful factors.
