Feb 27: You ovulate about 14 days before your period. If you have about a 28 day cycle, you would have ovulated and conceived about feb 27.

March 9th is 6 weeks back from your ultrasound which should be the conception date. If you have a long cycle 35d, this date is most likely

About 8 weeks ago: I would count back the approximate 8 weeks from the time of the sonogram to ascertain about when yoi became pregnant.

Since we date pregnancies from last menses not conception date, you actually would have concieved around 6 weeks prior to the ultrasound.
