Hallow madam, I have understood your situation. Low hCG level should not be taken lightly. The fact that it is increasing progressively suggests that the baby is viable. However the low hCG levels indicate that the pregnancy could be somewhere outside the uterine cavity, most commonly in the tube. In such cases, when the tube eventually ruptures, it causes an alarming intrauterine bleeding requiring immediate intervention. So please report to your Obstetrician and get investigated for ? ectopic pregnancy, ? normal pregnancy. I hope I have provided you the required information and the guidance.
