so confused!

hey everyone,
sorry if some of this is TMI or if its a stupid question. i'm still very new to this whole thing.
ive just realised i put the wrong dates here. i took my last BCP on the 14th of march (would have been up to the inactive tablets), and AF came on the 15th/16th- i wrote down the 17th but i know it came either the day after stopping the pills or maybe a day later than that. i've worked out that if i hadnt gone off the pill, i would have started my inactive pills on Thursday 12th april. my question is- do i consider this the date AF should be due? or still March 17th?? AF was fairly irregular before i went on the pill (usually came at least 2 days early) and my last cycle on the pill was very irregular, as i purposely skipped AF in late feb by going straight to the next pack and skipping the inactive pills, and it didnt work as i ended up "spotting" for the entire month (was basically a constant light flow period). now i'm confused about which date to go by when waiting for AF to come and knowing when to test and when to make a doc's appt!
sorry for the confusion!! should have checked more carefully.
