Hello doctor today is 16th day of my period . Ovulation happened on 14th day with ET of 9cm. We visited our gynaecologist as I had trigger shot on day 13 and next course of action . She said all is well and nothing to worry .. then suddenly she prescribed duphaston 10mg OD at night but again said it's not necessary as ET lining is fine but again thought for a while and says may be you can start for 10 days . I asked her should we take she again told the same it's not necessary but you can try . I am now confused should I take it or not as the gynec did not seem to be too strong on it . So confused and need your opinion . If we start it will be 3rd day post ovulation.
