my hormones are out of wack :(

so i usually always start my bc pack on a sunday. i get my period every tuesday on my sugar pills. in may i decided to skip my period for the first time because my bf was graduating from bootcamp the week i was going to get my period. so i skipped my period that week and then i mistakenly left my bc pills in the hot car all day (may 31st). my boyfriend and i had sex 3 times from june 1st-june 7th. we used condoms all 3 times and i took the pills on time. then i thought about leaving the pills in the car all day on may 31st and immediately freaked out. i got a new pack of pills on the 7th of june and started the new pack that day. i finished all the active pills and i thought i would start my period today (sunday) bc i took 2 sugar pills already but it hasn’t started....could my period be messed up bc of the pills or could i be pregnant...i don’t know if i should take a test or not bc i don’t think i could be pregnant....i pray it’s the change of my cycle. if someone could give me some advice that would be great! i’m only 17 and i’m usually smart about safe sex
