Reasons for Spotting During Pregnancy

Implantation Bleeding

Implantation bleeding occurs even before you detect the pregnancy. It usually occurs in about ten to fourteen days after fertilization. Implantation bleeding occurs when the fertilized egg gets attached to uterus wall. This is a very light bleeding that lasts for one or two days and many women might not even notice this, where as some others mistake it as the starting of menstrual cycle.

In some women, bleeding is noticed at around twelve weeks of pregnancy. This is because at this time, the placenta gets embed into in to the uterine lining and cause slight bleeding.

Vaginal Infection

Spotting can also be due to an infection in the vagina, like bacterial vaginitis or yeast infection or can be due to sexually transmitted diseases like gonorrhea, trichomoniasis, chlamydia etc.

Cervical Inflammation

An inflammation or irritation in the cervix due to internal examination, sexual intercourse or due to the collection of cervical smear may also lead to spotting. Cervical polyp may also cause spotting. Certain women experience cervical erosion which is the softening of cervix and cervical erosion can also cause spotting.


Spotting can also be a warning sign of miscarriage. Ectopic pregnancy, that is pregnancy resulted from implantation of the fetus anywhere other than in uterus or molar pregnancy, in which the abnormalities in the fertilized egg during conception makes the growth and survival of the embryo impossible, can also be the reasons for miscarriage. In all the above mentioned cases spotting or bleeding are the early visible signs of miscarriage.

Hormonal Imbalance

During pregnancy, usually the progesterone, which is the pregnancy hormone, covers the normal hormonal cycle of the women. But in certain cases, the level of progesterone won’t be enough to cover up the variations in normal cycle and such women experience spotting or bleeding approximately at the time when they would have had their menstrual cycle.

Bleeding in the Second and Third Trimester of Pregnancy

Placental Abruption or Premature Labor

In certain cases, the placenta gets separated from the uterus and cause bleeding. This happens when placenta develops in the lower part of the uterus close to the cervix. Placental abruption may cause miscarriage between 13 weeks of pregnancy to mid pregnancy, and premature labor between mid-pregnancy and 37 weeks of pregnancy. Placental problems may also cause bleeding even in the first trimester of pregnancy.

Dilation of Cervix

Spotting after 37 weeks of pregnancy is mostly due to the dilation and softening of cervix as a preparation for delivery. A blood tinged mucous discharge can also be noticed at this time.

If the spotting is associated with low back pain and abdominal cramping or if the bleeding is bright red in color, or if you have chills, fever and dizziness, then consult the doctor immediately, as it may be a more serious health issue concerning both the mother and the fetus.
