If you are pregnant, it can be confusing at first because early pregnancy symptoms can seem so much like regular period symptoms. Sore breasts, cramping, even a little spotting can either be a sign of pregnancy or that your period is about to start. I would probably wait until 33 days since your last period and if you haven’t started your period by then, take a test. I recommend checking out your local dollar or 99 cent store and buy two pregnancy tests there. It’s so much cheaper and they are just as effective as the one that are $15 at other places. They worked for me, and my sister, for both her pregnancies. Good luck!
