Hello. I have been fasting for 12 consecutive days (from 6 am to 6 pm daily) I did not have my period this month. Last month I got my period on 11th may 2016. It lasted for 6 days. But now its 39th day in my cycle and my period is 9 days overdue. I did a pregnancy test in the morning which came out to be negative. I wanted to know if is it too early to have test pregnancy? Is it because of fasting that my period has delayed so much days? Or is it because the HCG level is too low for the moment? Should I wait for one more week to take another test? Or should I consult a doctor to know the real reason behind my late period?
