Should I be nervous or should I just do what I can until it all resets?

So my job has a point system. It is a half point if you clock in even a minute pass the grace period which is 7 minutes and a whole point if you call off. Our points reset in July. I don’t call off a lot but from time to time I am late by a few minutes but as I said my job could care less and they still point me. I take public transportation so things happen. Which causes me to run a bit behind sometimes. I called off all of two times but my lates caused my points to add up to 7 and a 1/2 points. It takes 12 points to point out. I have 5 left but I keep thinking that all it takes is for something to happen on my way to work one time even after things going smooth for a while and I’ll have 8 points. Has anyone ever been in a similar situation with their job? Did you stress about it or did you just start leaving out a bit earlier
