Hugs sweetie!!!
I'm so sorry for your loss. Your feelings are completely normal, and the truth is that only you know when it's the right time for you to try again. I'm glad that your Dr. cleared you for TTC, and now you just need to try again when you feel ready. There's no need to rush it. We all fear it happening again, but as my husband said to me after the D&C - we want children, and so we can't let fear stop us from trying. And if there's something wrong, we'll figure it out. We won't have any children if we don't try! Chances are in your favor that it won't, so take as much time as you need, and then get to it!
Sending lots of good thoughts your way.... welcome to the board!
