It's only been a very short period of time since your miscarriage, I think I bled up til 10 or so days when I had my miscarriage before this bub & then the cycle was around 5 days longer.
Give it some time as your hormones need to reduce, they don't turn off automatically. Huge hugs, I saw exactly what you did with mine as well
Also if you're going to try again, I got pregnant the next cycle after I miscarried, so keep your hopes up
