I am 15 years old and my period was due on 1st february but it got delayed. I have an important religious occasion and wanted to delay my period. I took one primolut n (5g) tablet but was later told by a doctor not to do so as it is unlikely the medicine with work, and so I discontinued it's use. Will this tablet have any adverse effect on my health now that I have taken it? Is there any way I could delay my period safely?
