Hallow Dear, I would have appreciated had you mentioned the date of your last period. The fact that your pregnancy test is positive suggests that you are pregnant. However, faint second line is an issue of concern. The main causes of such weak positive test are: 1. Ectopic pregnancy: The pregnancy in such cases is implanted somewhere outside the uterine cavity, commonly the tube. Such pregnancy does not grow and subsequently ruptures to cause profuse bleeding in the abdomen. It requires emergency surgical intervention with many units of blood transfusion. Such condition is associated with extreme pain, which I believe you are having. Ultrasonography will help you. If in spite of positive pregnancy test, the uterine cavity is empty, it is most likely ectopic pregnancy. 2. Missed abortion of recent origin when the test is on the way of becoming negative. Ultrasonography can help detecting such condition. If detected, it needs immediate evacuation of the uterus. 3. Test performed too early in normal pregnancy. Subsequently it becomes strong positive. Weak positive pregnancy test, particularly with pain in abdomen should not be taken lightly and should always be investigated with ultrasonography. Please report to your Gynaecologist ASAP. I hope you got the message. Dr. Nishikant Shrotri
