12 days late

🙌🏼🙏🏼🤞🏼🤞🏼

So I am 12 days late n usually glow is on point with my cycles. My cycles are 40 days and this is the first time since it’s off I test when I was seven days late and it was a negative. Can I still have a chance?? Lately every morning I’ve been nauseous a little cramping and tired just not sure when to test again..
