...goes up in your body. This hormone is otherwise not present in our body. Pregnancy tests check a sample of your urine, and confirm your pregnancy if the hormone hCG is present in the urine.

Symptoms of Miscarriage

Symptoms for miscarriage may not always be the same for everyone, and it can be quite difficult to interpret the signs. Besides, some of the signs also occur even in a normal pregnancy, causing further confusion.

In a first trimester miscarriage, the fetus (baby) stops developing. Your body recognizes that the pregnancy is not viable, and starts shedding the lining of the uterus. This leads to mild cramping along with vaginal bleeding. These are the most common symptoms of a miscarriage. However, mild cramping and mild brown spotting can occur even without miscarriage in a normal pregnancy. What is of concern is when you have red and heavy vaginal bleeding. Call your doctor immediately.

Negative Result After a Miscarriage

Usually a pregnancy test will show negative after a miscarriage, that is, the hormone hCG will be missing from the urine or blood sample that you have given for testing. In some cases, only a trace amount of hCG may be present, but since the levels are almost negligible, it indicates that the pregnancy is over.

Positive Result After Miscarriage

Sometimes, even after a miscarriage has occurred, a pregnancy test may appear positive. This is because the hCG does not disappear from the blood immediately. Depending upon how far the pregnancy had progressed, the hCG may take up to 19 days to fall back to zero level.

Treatment for Miscarriage in Pregnancy

It is advisable to consult your doctor, who will conduct further blood tests and an ultra-sound, because there are various possibilities.

  • It is possible that the uterine layer has not been shed completely and some amount of tissue still remains behind. In such a case, you will need a D & C (Dilation & Curettage).
  • If you have been sexually active after the miscarriage, there is a possibility that you may be pregnant again.

Whatever the possibilities, you need to be totally sure of the diagnosis before you commence any treatment.
