so we have been TTC for 15 months now...and my periods are DOT regular..i have a 28 day cycle.. it has never happened that my periods get dealyed.. but this time i was supposed to have them on 4th Oct and I'm late by 3 days...

All home tests are coming negative..

and i dont wanna break my heart by a negative blood test too..

anyone? has anyone had negative urine tests even post missing period and a positive blood test??

How soon can a blood test detect??
