Two things!

So first thing, I had 2 different ultrasounds done by 2 different doctors. The first doctor said my due date is March 10th and from my ultrasound yesterday with my regular doctor they're saying it's March 8th. I know it's only 2 days difference I just don't know which one it is so I can keep better track of how far along I am. Second thing, at the other appointment the baby's hb was 177 bpm at 9w4d and now at 12 weeks the baby's hb is 155 bpm is that something to be worried about that the heart rate has slowed down?
