Stopped BC pills after 7 days...

I’m 28 and started BC pills at 19 years old for acne relief. Throughout the years, my acne hadn’t gotten any better until I stopped using the BC in November. Since then my skin has had a dramatic improve my in the cystic acne that i used to struggle with while on the pills that was supposed to help me. I decided to take them again just for a month to offset my normal period since I’m working at a family camp in two weeks and didn’t want to have to deal with being on my period while there. My period is regular and predictable when not on pills. I’ve been taking them since last Sunday and I am deciding to stop today, Saturday (I actually took my last one on Friday night, as I usually take them at night due to a history of nausea when taken during the day). In this past week I’ve noticed more cystic pimples and an extremely depressed mood. I’m curious if anyone has gone through something similar and what did your period look like for the next couple of cycles? Will I be spotting for days? What’s been your experience, related to mood and bleeding pattern?
