Ttc. 9 days late.

Whitney
Hello everyone. I'm am now 9 days late on my af. I took a hpt Sunday evening and this evening and both showed negative. Is it possible I could be pregnant and to early to show positive? I stopped taking my BC about 7ish months ago and since I stopped taking it my periods have usually been right on time sometimes a couple days late or so. But never been this late. Could I be getting my hopes up? If I don't start in a couple days when should I test again? Or should I test with first morning since both hpt I took I took them close to bed time?
