Get on an actual beginner weight training program. Self-programming and autoregulating are for experts; get on some pre-made, prepackaged shyt. Watch some YT videos on proper lifting form, even for benching and squatting. (I can almost guarantee your form ain't right.)
The biggest mistakes you can make as a noob in the gym are: 1) trying to call your own shots; 2) quitting before you make it a habit; 3) having poor exercise selection; 4) not eating enough/too much.
Using a proven program takes care of 1 & 3, now you just have to stick with it and eat to support your goals.
Each one teach one.
