If you are 40 days pregnant with no fetal heartbeat and low progesterone, you can have an ultrasound in a few days to detect fetal heartbeat and buds, and take progesterone supplements if necessary.
It is normal that there is no fetal heart and buds on the 40th day of pregnancy, because normally the fetal heart and buds can be detected on ultrasound only in 6~7 weeks of pregnancy, but low progesterone level needs to be supplemented, because progesterone helps the fertilized egg to settle and has the effect of preserving the fetus. Low progesterone level, you can actively go to the hospital for examination, under the guidance of professional doctors, further targeted treatment.
Pregnant women should also pay attention to more rest, eat some nutritious food, avoid strenuous exercise and prohibit sexual intercourse. If the doctor recommends supplemental progesterone, it should be noted that pregnant women with severe hypertension disease and liver and kidney disease should be cautious in using it, and pregnant women who are allergic to progesterone should be prohibited from using it. During the period of use, it is necessary to do regular ultrasound examination and laboratory test of progesterone level and adjust the medication under the guidance of the doctor.
