Relatively bad first semester senior year grades for a deferred EA student?

I had a few B’s freshman year, 1 B sophomore year, and no B’s junior year (the rest are A’s). But for first semester of senior year, I will have 1 B and 1 B+ for AP English and AP Physics respectively. This kind of ruins the upward trend and I’m worried that it will look like I slacked off senior year (even though that’s not the case). Will this lower my chances for competitive universities that I’ve been deferred at? Or am I just worrying too much?

It does depend a little on the prospective schools, and your intended major. But in general, you’re worrying too much:)
