Someone please help !!

Right so I stopped taking the pill in November and haven't had a period since October. Had a few days spotting in December and that's it's. If I was still in the pill my period cycle says I should of come on the 4th of January.... I've had nothing. I'm not too sure on what to do. I've done a test and its negative. Could I be testing early ? Maybe I need to wait a few months and let my body get use to not having the pill? It's driving me crazy 😳 please respond !
