Sometimes women experience the amount of bleeding that is not enough on the first two weeks of pregnancy, usually around the time of the expected menstrual period. Little bleeding is sometimes referred to as “implantation bleeding.” Doctors do not know for sure what causes this vaginal bleeding, but it may occur as a result of the fertilized egg implanted into the womb wall.

The amount of bleeding, the pregnancy rate, and symptoms related to anything can determine its cause. While bleeding during pregnancy does not indicate problems with the pregnancy, women who experience this should always be evaluated by a doctor. The causes are including miscarriage, abnormal location of the placenta, ectopic pregnancy, infection or cervical polyps, and premature labor. Chronic medical conditions and use of medications can also be associated with vaginal bleeding during pregnancy.

Abnormal bleeding is the flow of blood from the vagina that occurs at the wrong time during the month or on-short of the amount that is not appropriate. In order to determine whether the bleeding is abnormal, and the cause, physicians should consider three questions:

  • Is she pregnant?

  • Is she ovulating?

Every woman who thinks she has a pattern of irregular menstrual bleeding should think carefully about the specific characteristics of vaginal bleeding in order to help physicians evaluate the particular situation. The doctor will ask for the details of her menstrual history. Each category of menstrual disorders has a specific list of the causes, the purposes of testing, and maintenance. Each type of disorder is discussed individually below.

1. Is she pregnant?

Most abnormal vaginal bleeding during pregnancy occurs so early in pregnancy so that woman does not realize she is pregnant. Therefore, irregular bleeding that is new may be a sign of very early pregnancy, even before the woman is aware of her condition. It can also be associated with complications of pregnancy such as miscarriage or ectopic pregnancy.

2. What is the pattern of abnormal vaginal bleeding?

The duration, interval, and the amount of vaginal bleeding may suggest what type of abnormality that is responsible for the bleeding. Abnormal duration of menstrual bleeding may be prolonged bleeding from (hypermenorrhea) period, or too short from the (hypomenorrhea) period. Interval bleeding can be abnormal in several ways. Menstrual periods of a woman can happen too often (polymenorrhea) or too rare (oligomenorrhea). In addition, the duration can vary excessively from cycle to cycle (metrorrhagia).

The bleeding amount (volume) may also be abnormal. A woman can have too much bleeding (menorrhagia) or too little (hypomenorrhea). The combination of excessive bleeding combined with bleeding beyond the expected time of menstruation is referred to as menometrorrhagia.

3. Is the woman ovulating?

Normally, the ovaries release an egg every month in a process called ovulation. Normal ovulation is necessary for regular menstrual periods. There are certain clues that a woman is ovulating normally include the intervals of regular menstruation, vaginal mucus dirt amid menstrual cycles, and monthly symptoms including breast tenderness, fluid retention, menstrual cramps, back pain, and changes in mood. If necessary, doctors will order blood tests of hormones (progesterone levels), daily home testing body temperature, or rarely, a sampling of the uterine lining (endometrial sampling) to determine whether a woman is ovulating normally or not.

On the other hand, the signs that a woman is not ovulating regularly include prolonged bleeding at intervals after not having irregular menstrual periods for several months, low blood levels of progesterone over the second half of the menstrual cycle, and lack of normal fluctuations in body temperature during the expected time of ovulation. Occasionally, a doctor determines that a woman is not ovulating by using endometrial sampling with biopsy.
