The doctor suggests: 1. For “asymptomatic low progesterone in early pregnancy is it necessary to supplement progesterone”, if progesterone is low in less than 6 weeks of pregnancy, it does not indicate that miscarriage may occur, if it is more than 6 weeks, progesterone should be above 25ng/ml. If the gestational week is more than 6 weeks, you need to do the routine check: HCG, thyroid function, ultrasound, blood sugar, if the ultrasound shows intrauterine pregnancy, fetal survival, all indicators can be appropriate to keep the baby. 2, there are more than three miscarriage history, can be diagnosed as habitual miscarriage, but at present there are more than two times should pay great attention to, need to carry out a comprehensive examination before pregnancy: (1) comprehensive understanding of personal history, family history, genetic history; (2) couples chromosomal examination; (3) ultrasound to exclude the female reproductive system abnormalities; (4) infection factors, TORCH examination; (5) blood glucose examination to exclude diabetes; (6) thyroid function examination; (6) thyroid function examination; (7) the female reproductive system abnormalities.
