sronyx and lutera question

this might sound kinda stupid but is there a difference between lutera and sronyx? i am on my 5th month of being back on the pill and i filled my script at a different walgreens and i normally take sronyx and received lutera tonight. it took my body a long time to get used to the sronyx (constant bleeding) and finally a month and ive been normal again. im just afraid of starting something new and having the same problem again. if anyone knows anything about the difference between the two that would be great. thanks in advance.
