What is going on

I had my last period July 31, 2024

I tested around August 31st and all got positives

I started bleeding sept 7 and bleeding lasted for less than a week.

It’s oct 6 and I still haven’t started my cycle again after the loss. I been experiencing a lot of cramping, ALOT of fatigue and headaches for the past 2 weeks.

I had unprotected s** sept 19 and then again and again.

This is my test today but is it even possible to be pregnant again so fast after a chemical? Or is my body still healing from the chemical pregnancy. It’s such a bfp. I’m confused
