I am 30yrs old and have had a regular period since I have been 16yrs old. My period has been late 2 times and I have 2 children. My period comes between 7-9 every month. This month I has not came and now is the 12th. I ave taken 2 pregnancy test both have been negative could it be 2 early?

Yes, it could be too early for the test to detect the HCG if you are pregnant. Try waiting another week and then test again. Until that time treat yourself as if you are pregnant.
