There is no term as egg burst or anything. It's just that egg if not fertilized by ur husband at the particular time then it shrink and u bleed it out as periods.. Fertilization should occur in fallopain tube. Once fertilized ur egg will stick in uterus from where baby grows. For conception best period is from day 12 to day 16 of your monthly cycle. If u tell me the exact date of ur period then I ll tell the most productive days where chances of u getting pregnant is higher . U can contact me for further details if necessary for any queries.
