Taking 21 credits - Will this be looked poorly upon?

I’m interested in transferring to UW-Madison, and I’m currently attending a university in the UW system. Last semester I took some not so challenging coursework for a total of 18 credits (Intro chem, College Pre-calc/Algebra, Freshman english(required by my school even though I was at a sophomore standing)) and 2 Art courses for my major. These fulfilled gen Ed requirements and I earned a 3.83. I discovered my love of Chemistry and have decided to switch my major to Environmental Science. Over winter, I took and Anthropolgy course and recieved an A. Now I am in College Chem 1, Biology 1, 2nd Level Physics 1, Another humanities and the Freshman English 2 required course- which adds up to 21. I’m nervous my previous semester will not be considered impressive, but looking back I’m very happy I took the Chem course because I had no previous high school or college experience in Chemistry or Physics. I suppose I’m nervous on how the admissions process works, I hope it wasn’t a waste of time and credits. Currently have a 3.92, hoping to work my tail off in physics and bring that A- to an A. Also in 5 student orgs and work part-time (about 8 hours a week). I had a rough start to college and I’m hoping this doesn’t look like I’m breaking my back to get in, in reality I’m playing catch up. I’ve seen other posts where people say its quality of the course over quantity, but I don’t have the pre-reqs for the higher level courses. Will this also negatively affect my application or will they be understanding?

you are worrying too much.
