This is strange

Hi all. So this is a little strange but....

I lost my daughter at 15 weeks on 1/10. She measure 14 weeks and 3 days. I’d been monitoring my hcg levels via a HPT. Today, I’d been feeling weird and.....

This Thursday would be three weeks after her passing. I tested negative last week and now I’m testing positive????? I know this sounds dumb but I’m so dumbfounded. Is this possible? Has anyone else gotten a positive three weeks after m/c and it been accurate?

UPDATE: last weeks test is on bottom, todays is on top..???????
