Hello Doctor, Today is my 18th day of my LMP and having PCOD,i am on ovulation induction treatment. last LMP was 30-Mar-2014. My follicle got ruptured on my 16th day.We are having continuous intercourse from past 2 days. Now we have planned a trip to tirumala on may 4,5,6,7. Hopefully I need to conceive this cycle.If not how can i delay my cycle for another 1 week to 10days. Because if the fertilization has not occured then i might get my periods on may 2nd or 3rd.So kindly suggest or advise the necessary action to be taken.Thanks.
