It is possible to bleed in early pregnancy.  However, usually an ultrasound report gives the date of the first day of your last period, not a conception date.  Please be sure "conception" date is really what you are reading; it is unusual for an ultrasound to date a pregnancy from a presumed date of conception.  

Also, when was the ultrasound done?  If it was recent and you got pregnant six months ago, it is very normal for an ultrasound to be off by a few days.  Babies develop at different rates.  Only the earliest of ultrasounds can be counted on to be very precise.

You can look at a calendar and count back 8 weeks 2 days from the ultrasound date for a rough idea of when you might have conceived, or you can use a conception calculator online (just google the term "conception calculator.")  It does sound like the date given to you by the ultrasound was of the (presumed) first day of your last period, not the day you conceived.

Please read the part about how an ultrasound tells you the count beginning from the first day of your last period, not from "conception."

In other words, the ultrasound is not "off by two weeks."  It uses the medical way of counting a pregnancy, which count begins with day 1 of bleeding of your last period.  This does not mean it is "off", it is simply the way doctors count and time pregnancy.

I'd vote for the last April date you named, since you had a period April 8.
