Miscarried 4 weeks ago but two lines now??

Siobhan

I miscarried 4 weeks ago at 7 weeks. Just wondering if this test would show positive from that pregnancy as it’s so soon?? I haven’t got my period back again yet, only bleed for a week after the miscarriage.

I expected the test to be negative or at least a VERY VERY faint line from low hcg but it came up instantly as the wee went across. It’s very bright. Help?
