Early pregnancy refers to the first trimester of pregnancy when the placenta has not yet emerged and the embryo is unstable, so it is easy to have a pre-eclampsia miscarriage during early pregnancy. If the ultrasound reveals fluid in the uterine cavity, it means that there is bleeding in the uterine cavity that causes pre-eclampsia. Progesterone capsules or drospirenone tablets can be taken orally, and ramie root in water can be used to stop the bleeding. During the period of hemostatic treatment, absolute bed rest is necessary to preserve the fetus. It is necessary to go to the gynecology department of the hospital for about a week to review the ultrasound to check the absorption of the fluid in the uterine cavity. If necessary, you can see a TCM practitioner for a face-to-face consultation and prescribe herbal medicine for fetal preservation.
