Hi Mara, welcome to BB. I'm so sorry to hear of your loss.
I'm another with a similar story. Fell with DD and then after nearly 2years of trying fell again, but that bub left us at 12weeks1day. I was devastated and thought I never wanted to try again, but someone else had other plans and we 'accidentally' fell with DS the very next cycle.
Sadly there aren't any guarantees for any of us.
Good luck
