Positive after miscarriage

I had a miscarriage last month, I wasn’t far along but it was surprisingly hard. I was 4 days late for my period this month and got this positive. I’m happy but I’m really scared I’m going miscarry again. Is it common to miscarry twice in a row?

Edit* A little background on last month, I tested a few days before AF was supposed to come, and she did come a day late.
