Im always regular on my periods I always get it at the end of each month but last month got it on the 9 and this month I haven't got it yet and its past the 9. I took two home pregnancy test and were both nagetive could I be pregnant?

Do you know the length of your cycle... such as 29 days, 30 days? Are you using any sort of birth control?

Cycles can be off now and then, so that may be situation, but give it several more days and try another pregnancy test. Or wait until next month and see if your period shows; if not, test at that time.
