Is this even possible?? TW: Miscarrige

Sally

I miscarried on the 07/07

Stopped bleeding around the 13/07

Tested my HCG on 17/07 - tiniest line

Tested HCG again on the 22/07 - no line

Felt a little off today, thought why not just test…

07/08 - noticeable pink line.

It’s been only just over 4 weeks since I miscarried?!? Is this even possible??
