For bleeding at 10 weeks of pregnancy, first of all, ultrasound examination is needed to determine the survival of the gestational sac, and then blood HCG and progesterone test if the gestational sac is well developed. If the blood HCG and progesterone values are within the normal range, you can use Chinese herbal medicine for fetal preservation treatment, such as Kidney Fixation Pill. If the progesterone value is low, you can add natural progesterone, such as progesterone capsules and diethylstilbestrol tablets for fetus preservation treatment. There is also a case of scarred uterus with vaginal bleeding in the tenth week of pregnancy, when an ultrasound examination is performed to determine not only the survival of the gestational sac, but also the location of the gestational sac and the uterine scar. If the gestational sac is located very close to the uterine scar, the pregnancy is likely to be a scar pregnancy and it is not recommended to continue the pregnancy and termination of pregnancy is recommended.
