I have read conflicting information on when to calculate your due date. If I did my FET (5 day blast) on March 17,2020 some sites are saying Dec.24th and some are saying Dec 3rd. I know at first ultrasound they base it by size and growth, but has anyone had experience with this? If it is Dec 24 that will be such a blessing, it is my grandmother's birthday!!
Any help is appreciated!!!
