pregnancy bleeding

Fertilization occurs when a single sperm fertilizes an egg from a woman, usually in one of the fallopian tubes, and within 24 hours of fertilization, the fertilized egg begins to go through several stages of rapid division, and moves slowly from the fallopian tube to move to the uterus, There, the fertilized egg settles and implants in the lining of the uterus, and some women may notice small amounts of bleeding or spots of blood at the time of implantation.[1] This bleeding is known as Implantation Bleeding, and it is one of the initial symptoms of pregnancy, and its occurrence is considered normal and does not cause concern. Pregnancy cases only.[2]

Distinguish between pregnancy and menstruation bleeding

Pregnancy bleeding usually occurs 6-12 days after conception, meaning that it occurs around the time of the menstrual cycle, and accordingly some women may get confused, and they wonder how to distinguish between pregnancy bleeding and menstrual bleeding, and therefore it was important to point out Some of the signs and differences that help distinguish between them, the most important of which are the following:[2]

  • The nature of bleeding and its characteristics: The nature of menstrual bleeding differs from pregnancy bleeding in the following aspects:
  • Symptoms associated with bleeding: There are other symptoms that may accompany the implantation of the fertilized egg, including: feeling pain in the breast when touched, headache, back pain, nausea, suffering from mood swings, and minor pain or cramps in the abdomen so that it is less severe than menstrual pain . However, it should be noted that these symptoms can also appear during the period of ovulation or accompany the menstrual cycle, so it cannot be considered a definite indication that the apparent bleeding on the woman is pregnancy bleeding.
  • Color: A woman can often distinguish the color of the blood she bleeds during her period, which is usually between bright red to dark red. As for pregnancy bleeding, it often ranges from light pink to dark brown.
  • Thrombosis and blood masses: Pregnancy bleeding is not accompanied by the appearance of any blood clots, while on the other hand, menstrual bleeding is often accompanied by the appearance of some blood clots or masses.
  • Duration of bleeding: Pregnancy bleeding lasts for a period ranging from a few hours to three days, while menstrual bleeding usually extends for 3-7 days. Women who use birth control pills may have a shorter menstrual cycle.
  • The amount of bleeding: menstrual bleeding appears in the form of a noticeable and more abundant blood flow, and on the other hand, pregnancy bleeding appears in the form of spots or intermittent spotting, or a slight blood flow.

Other causes of bleeding

There are reasons or cases other than pregnancy bleeding that may cause a woman to suffer from bleeding during pregnancy, and the most prominent of these reasons can be stated as follows:[2][3]

  • Light bleeding: We mentioned that spotting or light bleeding is normal and does not cause concern if it occurs at the beginning of pregnancy, i.e. at the time of implantation, but there are other reasons that may lead to light bleeding in later times of pregnancy after implantation, and these reasons may not be alarming in some cases or more serious in other cases, and the most prominent of these reasons are the following:
  • Heavy or prolonged bleeding: It is important for a woman to note that heavy or prolonged bleeding during pregnancy calls for a visit to the doctor, whether it is accompanied by abdominal pain or cramping or not, and whatever the cause.
  • intercourse; Practicing marital relations during pregnancy can cause a woman to bleed at any time during pregnancy, due to the hormonal and physical changes that a pregnant woman goes through, and in most cases this type of bleeding stops on its own, without the need for any treatment.
  • Irritation of the cervix, especially after undergoing an internal clinical examination by the doctor.
  • Lifting heavy objects, doing a lot of physical exertion, or doing strenuous exercise.
  • Vaginal infection.
  • Ectopic pregnancy: An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, and this condition often causes the woman to suffer from bleeding, severe pain and cramps, and it should be noted that this case is serious and requires immediate medical attention.
  • Miscarriage: Approximately 15% of pregnancies end in the first months of pregnancy, and miscarriage is accompanied by the appearance of some symptoms such as heavy bleeding and cramps.
  • Molar pregnancy: It is one of the rare complications of pregnancy, which is represented by impaired growth of the trophoblasts; These are the cells that will later grow to form the placenta. Molar pregnancies can be divided into two types; The first type is a complete molar pregnancy; In this case, the fetus is not formed at all and the placenta cells are swollen and abnormal and take the form of a group of fluid-filled sacs. As for the second type of molar pregnancy, it is known as a partial molar pregnancy; In this case, some of the placental tissues may be normal and others are abnormal, and the fetus may form in some cases, but it dies at the beginning of pregnancy and cannot continue to live.[2][4]
