Hello; Ive been getting my period on the 26th for a few month. My last period was in October 26 to November 2.. I did not get it for last month and I'm still waiting for it to come.I don't have symptoms of pregnancy if anything I have period symptoms.I also took two pregnancy test that resulted negative.my question is why have i not started my period?.

Sometimes hormone levels will change and this can alter whether you ovulate in a particular cycle, which in turn can effect whether you have a period or cause it is a bit earlier or later than expected. It could be your cycle is just off and your period will start in the next several days.

When did you take the pregnancy tests? If you haven't taken one recently, maybe try again, or give it a few more days and then test. Many women, who are pregnant, will feel as though their period is about to start. If you test again, and get a negative result, either wait and see what happens when you would expect a period for this month or you could see your doctor for a test there.

Most pregnancy tests do not show well, until you are at least 2 week late. Sometimes even later. Also, always test, first thing in the morning, as soon as you wake up.

Also most often, there are not "pregnancy signs" until you miss a period, this is often the first sign, other signs start in a month of so later.

But, women are late, very late, or even miss a period now and then, not uncommon. So test again, and wait for next period. If you miss that one, see your doctor
