Last appointment today

Welp...my last ultrasound is today at 3:30...I'm already expecting them to tell me that the pregnancy has failed, and I may have my last chance to really hold onto any hope of this. I've never experienced a miscarriage before and I had a healthy child before this, I just don't understand how/why this is happening. I'm still spotting/bleeding with minimum cramps...but I keep feeling this "don't lose hope" feeling though. I pretty much lost the bloating in my stomach, my symptoms, my fatigue, etc. I keep hearing about misdiagnosed miscarriages but I'm sure I can't be that lucky. It's happening...and i have to accept that.
