Missed Pill?

Hi everyone! So i’m currently taking Junel Fe (don’t know the dosage off hang) but I had my period from May 19th - May 25th. That being said, I forgot to take my pill June 3rd and I woke up the next morning WITH AN ACTUAL PERIOD!! I still have it right now (June 9th) so it isn’t spotting it’s a legitimate period. Does anyone know if this is a pill related issue or has this happened to people before? My current Gyno SUCKS A$$ and I have to change doctors (that’s another issue) but someone please lmk if this happened to them beforeeee!!!
