my period came six days late

As long as you are getting your period you are not pregnant. If you are worried about being pregnant, take a home pregnancy test.

How light is your bleeding and how long did you bleed. I had very light bleeding but I still bleed around the time of my period when I was in fact pregnant you can have light bleeding around the time of your period during early pregnancy it's called spotting. Take a home pregnancy test not a line test those can be confusing. take it a few times because depending on how early your pregnancy may be it may not show up. or your period may have just "changed" that happens sometimes as well.

My period's are all messed up also. I use to get them every 28days for 5days then out of the blue my period's came on the 35th day for 5days and then the next time on the 40th day and now I haven't had them in 35 days and still waiting. Its weird my doctor's done heaps of tests and can't find out why ... I guess sometimes our body's do weird things.

My period usually comes on the 27th of every month. My period started today August 2,2011. Six days late, never have I ever been this late. How can I be certain it is a period and not spotting? And I have serious cramps is it okay to take medication for the cramps?
