AF question?

Megan
Okay so my husband and I have decided to start ttc, and last month I stopped usin bc (the pill) after my last cycle. This cycle, (first off the pill) AF was about 10 days late. However, I'm not even sure if it is AF because I had very light spotting yesterday (barely anything), but I thought it was AF starting. Yet, today there is nothing. I'm not sure if I'm making sense or not... Is this normal right after coming off the pill?
