Help; Senior year first semester GPA dip

So I currently am a senior in a “prestigious” private school. My school only sends in weighted GPAs, doesn’t allow anyone below junior year to take AP’s, and doesn’t have class ranks. I’m trying to use my extracurriculars and “upward trend” to appeal to colleges since I started freshman year with a 3.5, sophomore year with a 4.0, and junior year with a 4.5, which brings my GPA prior senior year to a 4.0/4.0 flat. However, my first trimester of my senior year dropped a little again to a 4.42. I’m applying to, and now I’m really worried about my chances. Could someone help me figure out how much this drop will affect my chances? Thanks!

If you don’t get in having a 4.42 in the first trimester of your senior year won’t be the reason.
