Mrs. Angelika Talar-Śpionek, since the Circlet replacement is cheaper, and they repackage it in a Nuvaring box, it's like a scam because it costs the same as the original Nuvaring.

I have the same situation, I bought Nuvaring, and inside a different product than usual Circlet. I wonder what it's about, because if the replacement is the same, why the price is the same. And why no one informed in the pharmacy. I have to put it on, because it's that day, but I've tested other albums and this one was the best, I hope nothing will happen and the period will be painless. It was the only album that I didn't have to take painkillers.
The changes are the worst.

To @Magda:

In the case of parallel imported medicines, the information is included on the outer packaging. There is, m.in, the country of import, the import permit number.
To prevent the situation from happening again, it is worth paying attention to this information or asking the pharmacist for help the next time you make a purchase.

I also recently bought a Nuva ring and a circlet inside. Since I put it on, I've had bleeding for 14 days, and in addition, I have such a rash on my face that I didn't even have when I was growing up. It seemed the same, but it totally broke my cycle. On the original Nuva ring everything worked like clockwork, and my complexion was like that of a baby. I'm devastated. I wait until the end of the series and go back to the original. It's a pity that there is no information on the packaging that there is another product inside. Now two albums will go in josh, and I have to buy the original ones anyway.
