Pill - mini-pill

I came off the pill on the 8th may.

I had withdrawal bleed like brown bleeding for 4 days 21st, 22nd 23rd & 24th May

Then on the 30th, 31st, 1st & 2nd I had it again? But like brown, but only had to wear panty liners lasted 4 days again

Is this normal? Or could it been period or another withdrawal or just spotting?
