No heartbeat how long until miscarriage

In general, the risk of miscarriage is much lower once the pregnancy has reached this point and a fetal heartbeat has been detected. Sadly, the reverse is also true. If you go in for an ultrasound, and there is no fetal heartbeat, there is a higher likelihood that the pregnancy will not be carried to term. Miscarriage is one explanation for no fetal heartbeat. However, there are multiple other reasons why the heartbeat of a healthy fetus is not being picked up.

There are a few possible reasons for the absence of a heartbeat on ultrasound. If you have no other symptoms, rechecking with another ultrasound seven to 10 days is the most common recommendation.

A transvaginal ultrasound an ultrasound in which a probe is inserted into your vagina to get better access to your uterus is generally much more accurate than an abdominal ultrasound in early pregnancy. Prior to eight weeks gestation, transvaginal ultrasound provides by far the best results. Finding a fetal heartbeat on a handheld doppler can take even longer.

You may be able to hear a fetal heartbeat with these devices at seven to eight weeks. Or you may not hear a heartbeat until you are 10 weeks along. If you are less than seven weeks pregnant, it's unlikely to find a heartbeat by ultrasound.

Using transvaginal ultrasound, a developing baby's heartbeat should be clearly visible by the time a woman is seven weeks pregnant. Abdominal ultrasound is considerably less sensitive, so it can take longer for the heartbeat to become visible. If you believe you are at least seven weeks along and have had a transvaginal ultrasound that did not detect a fetal heartbeat, consider whether your dates could be wrong. In early pregnancy, being off by a few days or having an irregular ovulation pattern can make a difference.

For example, if you did not ovulate exactly two weeks after your menstrual period started, there is a chance you are not really "seven weeks pregnant" in gestational age. This is true even if it has been seven weeks since your last menstrual period. If you have a follow-up ultrasound after a week and there is no change still no heartbeat , the likelihood of miscarriage is greater. But it may still be too early in your pregnancy for a heartbeat to be found.

If your periods were irregular, even though it is seven weeks from your last menstrual period, you may still be only five weeks along at a second ultrasound. If you are past seven weeks pregnant, seeing no heartbeat may be a sign of miscarriage. But there are many exceptions to the "heartbeat by seven weeks" rule. You've likely heard of people who were certain they had miscarried or were not pregnant, and then went on to have a normal pregnancy.

Since there can be exceptions and the approach you take next is extremely important, medical authorities have developed guidelines as to when you can be fairly certain you have had a miscarriage.
