Am I pregnant ?

Hi girls

My period is 15 days late

I did blood test when I was 10 days late but it was negative and I didn’t have sex since 11 August.

Do you think that 10 days late and 22 days away from the time I had sex is enough to detect if I’m pregnant or no?

I don’t feel any pregnancy symptoms, but I’m stressed out all the time since I missed my period 😫

I mean it’s blood test, 10 days should be enough, right?
