There is a lot of information out there about whether a period indicates you are 100% not pregnant. I have read almost every article you guys have and I am still a little confused and a Google search was not much help.

Is a period (that's comes at the time it's supposed to) considered an indicator that you are not pregnant?
Also, if not could you explain why. Thank you, just curious.

Yes. A period is a sign pregnancy didn't happen. This is because once a pregnancy didn't happen the lining of the uterus is shed to prepare for the next cycle, or the next egg. If the lining is shed, is impossible to sustain a pregnancy.
