Hi doctor. I need ur help. I was suffering from endometriosis and my ivf was also failure because the doctors could not find the heart beat of the foetus. Now I was under treatment and was having dinofirst tablets 2mg since 2016 and completed the course on 8th Jan 2017. In Dec my periods started on 28th Jan. But after stopping the medicine my period has not started yet. What is the reason? Am I pregnant?
