Those who have miscarried

I know this isn't something you may want to talk about and for those of you who have gone through something like this, I can't imagine and my heart breaks for you. I may not be alone in saying that miscarring is always a fear I have in the back of my mind. I'm currently 7w4d and I know anyone can miscarry at any time, but it seems around 6-11 weeks seems to be common for women who I've seen talk about it here.
