exciting

I missed a few pills last month. So there's a chance I could be pregnant. I've had breast tenderness and nausea for a week. Yesterday I was supposed to get my period, but it didn't start until the afternoon. I only had a little bit of blood when I was peeing, and nothing else. That evening, I did get a bit more bleeding. The smallest tampon was only half full. Normally, I get one that's almost completely full. And now, today at 4 PM, I have a small tampon that's only half full. I know it's not wise if I'm pregnant right now, but I'm still hoping for it. That's why I'm so scared to take the test tomorrow. I'm not sure if I should take the test. What do you all think?
