lupride injection is given 18-24 days after menses in preparation for ivf inthe next cycle.In case the lady becomes pregnant in the normal way,by chance, before the injection I am informed that it is harmful for the devoloping baby,if luppride isgiven.In view of this situation, is it possible to detect pregnancy by this time i.e., by say 20th day to avoid further process ? I am asking this question for my 34yearold daughter.
