I went and bought a first response rapid results im so anxious I want to take it now but I don't know what I am to do if its negative my period is due 10/10 or 10/12. My so called last period was chemical pregnancy bleeding and my last actual period was July 11th.... I'm completely confused on what day to go by for my next period... I'm going by the bleeding of my chemical pregnancy... for my ovulation it said I would have ovulated September 26th if I go by my last actual period. And if i go by the chemical pregnancy bleeding I would have ovulated the 28th.... so honestly I don't know which cycle to go by.
