It is not normal to see only dotted buds and no fetal heartbeat at 7 weeks in a woman with a regular menstrual cycle, but it is normal in a woman with menstrual disorders.
Early pregnancy women with regular menstrual cycle, as early as 35 days after menopause ultrasound can be seen in the intrauterine gestational sac, 6 weeks of gestation can be seen in the fetal buds and primitive cardiac tube pulsation, in the seventh week of gestation the fetal buds are about 1.0 cm long, and there has been a fetal heart, so when there is only a fetal bud and no fetal heart is not normal, but for menstrual disorders, the appearance of the fetal heart due to the long cycle will be delayed.
For early pregnancy ultrasonography suggests that the fetal buds are small and there is no fetal heart, under the guidance of the doctor to carry out blood hCG (human chorionic gonadotropin) and serum progesterone test, and according to the results of the test to formulate a treatment plan. However, pregnant women with menstrual disorders may not need to be treated for the time being, and the ultrasound can be rechecked in about 7 to 10 days as prescribed by the doctor when the general condition is stable.
