Looking for a hope

Hi ladies. I am looking for some hope. My cycle is normally 29/30 days. I had last periods on 15th sep. I went to gyne for some consultation on cd 12 . She did viginal ultrasound and told me that I already have ovulated on cd 10. Now it is cd 24 . Today I took hpt but it came negative. Glow says my periods will start tomorro but I know my periods will start in a week bc I hav 30 days regular cycle. Now tell me am I OUT or there are still chances of being pregnant???

Uptade: I did test at evening not with first morning urine.
