Still testing positive

I had a miscarriage starting July 10th and completing the 13th. I got my period July 14th and just finished. The past 3 or 4 days it has just been some spotting.

I was told by someone on here (don't remember who) that my husband I could start trying again after I stopped bleeding and I stopped testing positive.

This was taken just now at 6:50 pm. It's still a decent line. I was only 5 (ish) weeks when I miscarried. When will I stop testing positive? When can we start trying again?

We both feel ready but we don't want to mess anything up or be unsafe.
