For those that may not know, the way drs count weeks in pregnancy is not from the moment of conception, it’s from the first day of the last menstrual cycle *before* conception. So at “5 wks”, conception happened a few days to 3 wks prior & most people don’t know they’re pregnant. https://t.co/5RpYPWKSX1
