Pregnant right after miscarriage???

I’m a mother of 2 (3yr old boy, 1yr old girl). I had my first miscarriage in October. I was 16 weeks when I found out the baby had stopped growing at 13 weeks. I had to deliver and found out it was a boy ♥️. My placenta wouldn’t come out so I ended up getting a D&C. I’ve had one period since then, and I’m 6days late for this cycle. I’m not sure if I’m pregnant again or waiting on my body to get back on a regular schedule. I’ve always been very in-tune with my body but this is confusing for me: physically and emotionally.
