I haven't posted on this forum before and I'm a new novice cellist (6 months) but so much goes in to answering your question.
How old are you, have you played any other instrument, another stringed instrument, do you read music already, is your teacher a good fit, is your instrument serviceable? How much time do you have to practice and do you use it wisely?
I'm guessing your questions are more about are you progressing appropriately, maybe even if you should continue.
A lot depends on your goals. I'm taking lessons in late middle age because I love the steep learning curve in the first year or two of learning any new skill.
My goal is to jam with my kids and maybe play in church once in a while.
First think about what your goals are in studying cello, then talk with your teacher about whether you are on track to achieve your goals. If not, you may need to change some of the factors I listed, or adjust your goals.
The other thing to think about is how much pleasure you take in your playing. "Just for fun" is a perfectly good reason to continue to play.
