My cycles are a bit irregular so im not fully sure when it actually happened. The doc gave a due date from the scan but i still wanna understand how to figure the conception date. anyone know how its calculated?
My doc said conception usually happens around ovulation, roughly 2 weeks after the first day of your last period in a regular cycle. But the scan gives the most accurate dating. She corrected my dates after the first ultrasound actually.
I wondered the same thing. They told me conception is approx 2 weeks before the date the doctor counts as your pregnancy week. Confusing but the scan sorted it out for me.
I tracked my cycle on an app so I had a rough idea of my ovulation window, which is around when you conceive. But the early dating scan is the real confirmation, trust that over guessing.
