Worried about my first statement

hi I’m just starting out with my first credit card (discover it college) I got about a month ago (around the end of March/ stat of April). and per my sister in laws advice I’ve been making a small purchases with it (food, and snacks) then immediately paying it off as soon as the payment is posted. and because I want to build good credit I haven’t spent more than 9% of the credit card’s limit before the balance goes back to norma. however an issue arises where I haven't gotten a statement from them yet, so my worry is if I am doing something wrong. please let me know if there’s something else I should be doing to boost my score up, when I can see my credit score, and when I should be paying it?
