Could Delayed Period And Watery Pink Vaginal Discharge Indicate Pregnancy?

I am trying to get pregnant. Since à miscarriage in sept my cycle has been shorter (24-26 days instead of regularly 27) I have used an ovulation kit to work out when thé best time to try is. My period is now 9-11 days late and i have a light watery Pink flow. Could i still be pregnant or is this definately à period ?
