Second set of twins

So I had twins I delivered July 29 2016 and one was stillborn from ttts we knew he was going to be stillborn because he had passed the day offer laser operation that whole experience from the moment I found out about the ttts was the worst experience of my life and scariest thing ever! I faced all of my biggest fears and now I am 7 weeks pregnant with twins again!! I am so scared and excited all at once I can't imagine going thru that again...
