Weird symptoms after stopping birthcontrol

At the beginning of this month I stopped taking my birth control pill due to having a three week long period. I have been getting a lightheaded/dizzy feeling and light headaches on and off all day for the past week & I have also been getting what feels like low blood sugar before I eat and I get super shaky & nauseous. Could this be from stopping my pill? I don’t think I would be pregnant, but I know it’s always a possibility. I’ll take a test this week if the symptoms don’t stop, but I was just wondering if anyone else has had this happen?
