breastfeeding and dizzy

Hello, I know periods can be hit and miss while bf. I had one November 13, and if I count it right I should have started last Friday. I had really tender nipples last week that has subsided partially. I've had cramps but no bleeding and increased urination. though I drink a lot so idk. I took a test and thought maybe I saw something but maybe I'm crazy. should I wait? Or would it show by now?
