Periods after miscarriage

Hi ladies! I had a very early miscarriage at 5 weeks on the 5th November, my next period came 4 weeks after. 25 days into my next cycle, I had some red and brown spotting for 5 days which then tapered off. I then had a normal period at 38 days which lasted 5 days. However now, 14 days into this cycle, it looks as though I am starting another period! This is all heartbreaking as we want to TTC again straight away as that was our first ever pregnancy but we can't when I'm like this! Does anyone have any idea why I'm like this and what it could be?
