Taking pregnancy test 6 days before missed period

Sonia

Hello,

I just wanted to know what you guys think or if you’ve ever experienced this. I had a miscarriage at 6 weeks pregnant back in November 2020. I tested last night and got the result that is on the picture attached. This morning I took another test and it was very very faint, I could barely tell it was there compared to the one I took last night. Is it possible it could have been a false positive? Today I am 5 days before my missed period.
