Hi, Thanks for the query. I understand your concern.  Usually date of conception calculation is based on date of last menstrual period & the regular length of menstrual cycle.  As your cycles were irregular you can use other reliable parameter - the USG scan in early weeks of pregnancy to calculate your date of conception. Usually early week USGS show exact age of fetus than the USGS done in later months.  Thanks.
