Discouraged and confused

Olivia

I took two pregnancy tests a few days ago. Both came out positive, faint positive but still positive. I took a clear blue digital yesterday and the day before they both said not pregnant.

Someone said you can get a not pregnant with clear blue, because they take a lot of hormone. I am a day before my missed period and I haven’t had very many symptoms of getting it at all.

Could I be pregnant just not enough hormone yet to detect ?
