Early miscarriage..

Hi all, I'm new to this group. The last three days I had faint positive tests. Early this morning I started bleeding moderately and had awful cramps. Only a couple small clots but I think I had an early miscarriage, couldn't find a line on the test today :( Although we are not actively ttc right now we will be soon, so it is discouraging. I am now feeling worried that when we do start really trying it will not happen.
