Monday morning at 11 am have done follicular study which shows egg size 21mm...doc had given me hcg injection on monday night at 9pm but told me not to keep relation on Monday then i have done follicular on tuesday 2pm and egg was ruptured at that time n kept relation on tuesday at 5pm... But what if the egg was ruptured on monday at 2pm then its more than 24 hrs coz i kept relation on tuesday at 5pm (read somewhere that egg stays only for 12-24 hrs) Is there are chances of conceiving ??
