Help is this normal

I threw up 2 mini pills, missed my period for two weeks, spotted for 2 and a half days lightly bled for 2, stopped then 6 days later started spotting/bleeding again (bc packet says period due in 3 days but I already bled 6 days ago) is this normal!? Help (I’ve been on this bc for over a year but stopped for a month or so and I’ve been on it again for 4 months)
