Worried about this semester's grades.....how will UC's view this?

I am currently at a CCC about to transfer. I currently have a 3.5 GPA and i applied to almost all UC’s except UCR and UC<. Everything on my transcript looks fine, A’s and B’s, but this semester has been really hard for me due to having to go off ADHD meds for a bit (medical insurance changes). This means i might get C’s in all 3 of my 5-unit classes (chem, bio, and calculus) which will bring my GPA to around a 3.0. If I explain my circumstances for this semester (I will be on my medication next semester, aka my last semester at CC), will that matter at all in admission decisions? Also I applied to all UC’s as a psychology major so none of those classes are pre-reqs or required at all for that major, if that makes any difference. I’m just taking these classes because I switched my major from psychology to biology last semester for some reason (regret it now) and am taking the classes for the bio major.

Sorry that this is a bit of a mess. I’m really stressed.
