depression?

I recently started the pill. I have noticed feeling down a lot lately. I don’t want to go to school or talk to anyone, I don’t bother with homework, my grades are slipping, I don’t want to get out of bed, all I want to do is sit in my room alone. I miss summer so much. like unhealthily. the weather, the freedom, the no school, no stresses. I don’t know if I am just fed up with school or if the pill is causing mild depression. has anyone experienced something similar?
