Are these any good?

I bought these a month ago to track my ovulation and they worked good! It showed u was ovulating around the same days as my GLO calendar shows. I’m not keeping my hopes up since I’m only a day late in my period, I know it could be anything but I read reviews that these are not good to check HCG. Some reviews showed that they were confirmed pregnant by the doctor and these tests still showed a negative. Has anyone used these or any reviews overall? In case I’m not pregnant I can perhaps buy a better brand.
