negative test but feel like crap

Tina
AF due Nov 5 or 6 depending on the app. Took a test today, vvvvNegative (tore it apart and everything lol) 😩 just wanting someone to tell me something encouraging. I used FRER 6 days sooner. I'm very nauseated and super tired.. been having cramping but I know all these things could be pre-period. Hope not! I hate the TWW
