Could I have just ovulated? Later then I thought

Beka

So my period is a couple of days late I went to a pregnancy care center and there hog urinalysis came back negative but she also told me if I don’t start to come back at the end of the week is it possible I just ovulated leader in my cycle and I could possibly still be pregnant with this mess. Or do you guys just think I’m not pregnant and my period will start.
