I’m so confused

Alyssa

Period is 13 days late today.. I have very very sore breast, exhausted is an understatement, on/off nauseous.. I’ve taken 4 FRER on different days with different urines since Friday! They have all had VVVFL on them, and even had a blue dye test show a faint line (cheapie) — but lines aren’t getting darker. Done a digital and it said “NO” — Should I do blood work?
