I had miscarriage on Christmas

I was 5-6 weeks

I’m now cycle day 36

Which is not like me at all but knowing it is possible to take 4-6 weeks for period to return

Anyways I broke down and took a digital clear blue test and it came up negative but I took it apart (I know!! I know!! You shouldn’t but I did) and I think I see two lines

What are any of your experiences if you took apart a dig clear blue and had positive lines

Did you go and test with a first response??

Did you test again in few days??

Thanks in advance
