The absence of fetal heartbeat at 7 weeks of pregnancy may be a normal condition and there is still hope. Pregnant women should not worry too much and just continue to follow up and review. If you are a woman with regular menstruation, i.e. the usual menstrual cycle is 28-30 days, usually the fetal heart appears at 6 weeks of pregnancy, but due to individual differences, some pregnant women may not have a fetal heart until 7 weeks, which is normal and there is no need to worry too much, just have an ultrasound examination after 1 week. For women with irregular menstruation, long menstrual cycle or delayed ovulation, the appearance of fetal heartbeat will be delayed accordingly, and it will appear at the latest at 9 weeks of pregnancy. Therefore, if the fetal heart does not appear at 7 weeks of pregnancy, do not worry too much, it may be a normal situation. A pregnant woman can be observed until 9 weeks of pregnancy at the latest, and if the fetal heart does not appear by then, it may be fetal abortion and the pregnancy needs to be terminated.
