A rough morning turned out alright!

I'm 8w1d according to my lmp and app. Been having some spotting the last two days and it was red this morning with cramps. Rushed to my doctor. So worried and scared. We saw our little bean and the heart flickering. Didn't get to hear the heartbeat. I measured a week behind at 7w1d but the doc didn't seem worried. I was told to keep my confirmation appointment next Monday and my due date could change.
