Pregnant Maybe?

I need help. My last period was September the 22nd, I didn't have a period for the month of October. My period for September was really light and very little blood. But not too little to make me worry. I waited for my period in October but it didn't come. I took a pregnancy test a few weeks later and it said no. I waited another week and it also said no. Im going to be taking another one soon, and my period should be coming up soon. Do you think I'm pregnant. If you need more information, my email is thank you so much.
