Good morning. I recently found out I'm pregnant. I had my LMP on 14th April 2018. I have irregular periods, which I see about every 21 days( not always 21, sometimes less).They usually last for 5 days. I used the online conception calculator and it has my possible conception date from the 16th April to the 21st April,(the 21st April is also my ovulation date.) I just would like to know my possible date of conception please.
