Some signs of ectopic pregnancy

Many people mistakenly think it is menstrual blood, but it is blood that indicates an ectopic pregnancy. This abnormal bleeding phenomenon has many different characteristics from menstrual blood such as: lasting for many days in a row, bleeding little by little, blood does not clot and is dark red. There are very few cases of women having an ectopic pregnancy without this sign. Abdominal pain: This is a characteristic symptom of an ectopic pregnancy. So how long does an ectopic pregnancy last? Many people experience abdominal pain early in pregnancy. Abdominal discomfort, accompanied by constipation. After that, the mother will feel severe abdominal pain on one side, pain for many days without stopping. If abdominal pain is combined with unusual bleeding, you need to immediately think of signs of an ectopic pregnancy. The concentration of HCG in the ectopic pregnancy in the blood decreases gradually: In a normal pregnant woman, the concentration of HCG will increase gradually with gestational age. The larger the fetus, the higher the amount of HCG in the blood. However, in women with an ectopic pregnancy, HCG levels will rise slowly, or even not, at all. Therefore, some women realize that they have signs of pregnancy but the test still shows only 1 line, which can also be suspected of ectopic pregnancy.
