Nuvaring period

Soo … im on nuvaring and i normally do one ring free week at the end of the month but this time i kept my ring in the whole month to avoid having a period. I was out of town when i was suppose to insert my new months nuva ring but since i was out of town i didnt have my ring with me 😣 i completely forgot to stop by for the ring before i left out of town so i kept it in for another 1 week and like 2-3 days before i put in the new ring . Basically i inserted the new ring 1 week and some days late and ever since i last inserted the ring like about two weeks ago iv been bleeding kind of like a period … would this be because of how i ised the nuvaring incorrectly? Or break through bleeding ? This sunday i have to take my ring out to get this months period but iv been bleeding lightly since i lst put the other ring on two weeks ago. I hope i make sense 😭 someone help !!
