Pregnant after a misscarriage

Sammi • Married to my bestfriend and pregnant with a baby boy, due Feb. 6th 2016

So my husband and i just found out that i am 6w5d pregnant with what were hoping to be our rainbow baby. I misscarried back in February and i was so excited when i found out. I feel horrible tho because part of me isnt excited at all because im scared to get my hopes up for anything bad to end up happening. I mean i know i should be overwhelmed with joy but i just cant bring myself to it. Even after seeing the baby being so much more developed than the first pregnancy and the little heartbeat im still a depressed nervous wreck. How do you stay positive so soon after a misscarriage? ??? :(

The first ultrasound picture is the first pregnancy taken at 7 ish weeks. And the second ultrasound is the current pregnancy taken at 6w2d.
