At four months of conception, you usually can’t feel fetal movement, and it takes five to six months to feel it. It is recommended to take regular routine pregnancy tests, eat a diversified and balanced diet, and pay attention to ensuring sufficient and good sleep and maintaining a positive mindset. As long as the pregnancy test indicators are normal and there are no uncomfortable symptoms such as vaginal discharge, abdominal pain or back pain, there is no need to worry and take other interventions. In the fourth month of pregnancy, you can go to the hospital to do a Down’s syndrome screening or 4D ultrasound and other auxiliary examinations for detection of malformations.
