Clear blue digital?

Chantél

Heya. So Im 4 days before period. I had a faint line on asda tests x2, and now i took a clear blue digital and it said "not pregnant" im 10dpo so im thinking maybe its too early to show as digitals need more hcg?? Anyways.. I know youre not meant to but I opened it up, and have 2 lines?? Does that mean my hcg is not strong enough yet x
