My period last month was kind of later than I'm usual.. I got it on a thursday and it was very light and didn't last long. This month I usually get my period on a tuesday/wednesday and it's gone by the weekened.. well it's almost the end of thursday and I still haven't gotten it. I am on birth control and the last time I had sex was last month on the wednesday that my period was supposed to show up on. I bought a pregnancy test, but have to wait till tomorrow morning to use it. I haven't felt sick or any different in the past month.
Can anyone explain what could be causing this? Or if it's signs of pregnancy?
