Im seriously trying to understand strip tests vs the normal store bought pregnancy tests bc I’m getting super confusing results.

Saturday - easy @ home hcg strip test - vvvfl positive

Monday - 3 easy @ home hcg strip tests that all agreed who posted that they were positive. I also had a negative clear blue digital but was told not to stress

Tuesday - 1 easy @ home hcg strip test - faint line positive

Today - 2 easy @ home hcg strip tests with positive lines BUT the first response early result has NOTHING 🤦🏻‍♀️🤷🏻‍♀️ photos below

Making me nervous - does anyone know how accurate the easy @ home strips are (I know what they say online but what about real life?!) could I be seeing an evap or dye run on those and the FRER is accurate?

Af still hasn’t come (scheduled to start Monday). Ive had nausea (no vomiting) since 5/29. Constantly yawning but no real “tired” feeling with mild cramping and no other symptoms (down 1lb due to lack of appetite from nausea, no breast soreness, no spotting, etc) right now am showing to be 15-16dpo

Ladies - any ideas would be appreciated! First time (hopefully) mommy and actively TTC so it’s all stressing me out!
