What causes bleeding during 12 weeks of pregnancy?

Women can be very nervous if they experience any symptoms during pregnancy, not knowing whether this is normal. For example, if you bleed in the twelfth week of pregnancy, the 12th week should be considered the early stage of pregnancy. If you bleed at this time, is there any problem? Is this phenomenon normal? Is there any disease that could cause the bleeding? Below, I will introduce several possible reasons for bleeding during the 12th week of pregnancy.

1. Ectopic pregnancy

An ectopic pregnancy is when the embryonic sac implants outside the uterus instead of inside it. The conceptus that implants outside the uterine cavity cannot develop normally, and the ratio of estrogen and progesterone in the body changes, causing the decidua to separate and leading to irregular vaginal bleeding. Ectopic pregnancy must be dealt with as soon as possible, otherwise it will become more dangerous as the embryo grows larger, and may even lead to death due to rupture and heavy bleeding from the ectopic pregnancy.

2. Miscarriage

Once there is bleeding or other miscarriage symptoms in early pregnancy, medication will be prescribed to help maintain the fetus after the intrauterine pregnancy is confirmed. The tocolytic drug given in the early stage is progesterone, which can help the placenta implant tightly to avoid miscarriage.

In addition, inflammation can also lead to miscarriage. When vaginal discharge increases, the vagina becomes itchy, has a foul odor, and is yellowish in color, it indicates inflammation. Regardless of whether you are not pregnant yet or in the early stages of pregnancy, if there is inflammation, you must see a doctor to cure the disease, otherwise it may cause premature birth or even miscarriage in the future. About half of miscarriages are caused by chromosomal abnormalities. The human body will reject the abnormal chromosomes. This is natural elimination and should be viewed with a normal mind.

3. Improper implantation position

Although some embryos implant in the uterus, they are in the cervix or uterine horn, which is called ectopic pregnancy. They often cannot grow and develop normally and lead to miscarriage.

4. The placenta is implanted too low

A normal placenta is attached to the bottom, posterior wall, anterior wall or side wall of the uterus; if the placenta is attached to the lower part of the uterus, or even the edge of the placenta reaches or covers the internal os of the cervix, and its position is lower than the presenting part of the fetus, it is called a low-lying placenta or a previa. In the former, the placenta will naturally pull up as the pregnancy progresses, and will have little effect on delivery; in the latter, there will be painless vaginal bleeding during pregnancy, and a clear diagnosis must be made before delivery.

5. Pregnant women are too tired

If a pregnant woman experiences a small amount of bleeding each time due to being too tired or under a lot of work pressure, the symptoms can be improved by simply resting in bed more. Although bed rest is the best way to keep the fetus safe, when bleeding is first discovered, it is best to ask a doctor to identify the symptoms to avoid missing the opportunity for treatment.

The above five situations may cause bleeding in the early stages of pregnancy. Therefore, if bleeding occurs at 12 weeks of pregnancy, you must go to the hospital for examination to make sure it is not caused by these reasons. At the same time, you should also pay attention to rest, ensure sleep and diet, and avoid overwork. At the same time, pregnant women are also reminded to keep a relaxed and happy mood and not to be too nervous.
