HCG level dropped in the second week?

This is definitely a question that would be best answered by your doctor but all I can say is don't worry too much and don't give up hope before you have to. I have heard of some women's HCG levels remaining extremely low in the first trimester that they did not even know they were pregnant because the pregnancy tests couldn't pick up such low levels of HCG and they went on to give birth to healthy babies..Good luck to you and make a list of questions for your doctor and bring it with you to your next appointment.
