Ultrasound 3 tomorrow

I should be super excited to see baby tomorrow, but as I get further along I get even more scared. My last pregnancy ended at 26weeks when my baby boy was born sleeping. I found out his heart had lots of defects at 13 weeks. I am going tomorrow at 12 weeks 6 days for them to take a peek at this little babies heart and to measure it's neck. I hope all is well. If you could keep me in your prayers tonight i'd greatly appreciate it. Thank you!
