Took plan b 3 times within 3-4 months

How badly is it going to mess up my period? I got an early period when I was supposed to ovulate for 3 days and then 2 weeks later I got my normal 7 day period and I was supposed to start my next period October 1st but it still hasn’t came... And before you bash me in the comments my boyfriend at the time made me take them to be safe.
