Hi doctor,
Few weeks ago I did blood test for vitamin D and it showed that I had 3 while it should be between 30 to 70 range. So my doctor prescribed 12 doses of architol injections ( 1 every week ) and shelcal tablet daily after breakfast . Till now I have taken 3 doses of injections and now this month my period is late by 10 days and it still has not come. I also had exams this week but now they are over, so I don't think stress can be the reason for the delay as it has never happened before. So can this be a side effect of the injection? Please help.
