Hallow Dear,
The first test you performed was rather too early, hence confusing results. Ideally, the
pregnancy tests on urine should be performed 8-10 days after missed period on overnight early morning first urine sample for reliable results. Done earlier, the tests may be false negative. However, there is another test - Beta hCG test which can give reliable results even few days before missing period.
However, even after 8 days you have got the faint positive line; i.e. weak positive test, it suggests that the hormone hCG is low. This happens commonly in following conditions:
1. Test performed too early - may be delayed conception.
2. When the baby has become non-viable. This is known as
missed abortion. Then hCG gradually starts declining and hence week positive test.
3. Ectopic pregnancy: In this condition the baby is implanted somewhere outside the
uterine cavity, most commonly in the tube. It is a very serious condition. Subsequently tube ruptures and causes alarming bleeding. It needs
blood transfusion and surgical intervention.
The best option for differential diagnosis is
ultrasonography.
In normal pregnancy, intrauterine sac will be seen with foetal cardiac activity.
In non-viable baby (missed abortion), the foetal heart will be missing and sac will be irregular. In such cases timely termination of pregnancy is indicated lest the serious complications like threatening bleeding due to clotting defects (DIC), infection, kidney failure, etc.
If the uterine cavity is empty in spite of (weak) positive test, it indicates that the
implantation is somewhere else; i.e. ectopic pregnancy.
Laparoscopy will help to confirm the diagnosis. If it is unruptured ectopic pregnancy, it can be managed by laparoscopy only.
Please report to your Gynaecologist and undergo ultrasonography for correct diagnosis and managing the pregnancy appropriately.
I am sure this helps you.
