Period is late..

Ka

I’ve had regular periods my whole life and we have been TTC for 2 months now and the first month I started on my normal Thursday and this month nothing. I’ve cramped a few times in the beginning of the week but never started. I’ve tested twice now and both negatives with 2 different brands. And now I’m not have any symptoms of starting. Has anyone ever had this and still been pregnant or just started later?
