I missed my period I had in 5/10 usually I have a normal if , but I had a flu these month , no Temperature just little runny nose an through, now I missed my period already 10 days I took a pregnancy tests and its negative , can I be steel pregnant or maybe it was not enough urine , or because of I had a flu?

It's possible that you are pregnant and it's too early to register on the HPT. When using an HPT make sure you use first morning urine.

But I am 10 days late
I was expecting at 6/8
