If you are pregnant for more than 40 days and have reddish blood, first of all, consider that it is a case of pre-eclampsia, it is recommended to take proper rest, keep your mind calm and don’t be overly nervous; then you can take proper progesterone supplementation; in addition, you also need to carry out ultrasound examination of the obstetrics and gynecology department, to make sure that it is an intrauterine pregnancy, and to determine whether the development of embryo is in line with the number of days after the menopause. After pregnancy, there will be menopause, early pregnancy reaction, breast swelling and discomfort, frequent urination and other early symptoms, through the monitoring of blood or urine HCG can determine whether pregnancy. Blood and urine HCG levels can also be monitored to determine the activity of the embryo, but ultimately an ultrasound examination by an obstetrician/gynecologist will be necessary to determine if the pregnancy is intrauterine and to determine how well the embryo is developing.
