I had my follicular study done, this month. I was given Hucog 10000 IU (HCG) injection on my 12 & 13 rd day and my follicle ruptured on the 14th day. I want to know, for how long will the egg released after the rupture be alive? In normal circumstance, it remains alive for 24 hours. But will the injection given to me, increase the lifespan of the egg released? Also, now I have been prescibed tablet, Duphaston 10mg, for 15 days and today is my 15th day. Will this increase the chances of me getting pregnant?
