Coming off birth control

So I’ve recently come off the pill Rigevidon. I finished the packet properly then had my period and didn’t start a new packet. I’ve been off it the past week and a half and ever since I’ve come off it I have moments where I feel light headed, become really dizzy and have heart palpitations almost feels like a panic attack I’ve been to the doctors had an examination and they said everything is normal I have an upcoming blood test. Has anyone else experienced this when they’ve come off the pill??
