If the bleeding occurs around one month of pregnancy and is not menstrual, the bleeding is generally considered to be related to preterm miscarriage and embryonic instability. Early pregnancy is the peak period of miscarriage, if the pregnant woman does not rest well, emotional instability, low progesterone, and the quality of the fetus is not good, it will easily lead to bleeding. So don’t be careless about the bleeding, go to the hospital for further examination, including ultrasound, and blood test for progesterone and HCG, etc. In addition, if the pregnancy is unplanned, bleeding and abdominal pain may occur at this stage, so it is important to determine the size and location of the gestational sac. Most pregnant women who have miscarriage symptoms in the early stages will have an effect through birth control treatment, but there are also cases of unavoidable miscarriage due to particularly heavy bleeding.
