I feel weird.

I stopped the pill in early November. After that, my period came back to normal and ended when I expected it to.
So, I should have gotten my period again on December 10th. I took a test then, and it was negative. I think I'll just wait for my period to start and then try again. But now, three days later, I still haven't gotten my period. However, I've had some vague symptoms for a week now, like bloating, nausea, and if I don't eat in the morning, the nausea doesn't stop (while before I never could eat breakfast because it made me nauseous). I also have headaches, sore nipples, and difficulty with bowel movements. I'm just not brave enough to take another test because I'm afraid of the disappointment. Sometimes I even start wondering if these symptoms are just in my head and that I actually want to feel this way. I do know that when you've just stopped the pill, your period can be irregular. Should I test again at the end of the week if I still haven't gotten my period?
