Help please

. Has anyone convinced the first month off the mini pill? Basically period 5th of may to 10th of may. I stopped my pill the 10th of may. Had withdrawal bleed the 16 to 18th of may. Now I'd b due first week in June and nothing?? Very sore boobs though not sure if that's just part of coming off it? Do I go by withdrawals bleed as period date?
