Anyone else feel their mood is low on mini pill?

I started taking the mini pill cerezette about 12 days ago and up until this point I felt great but the last few days I feel like my moods lower and I'm just feeling it down. I just feel I'm taking things more personally and over thinking everything. This is def not PPD my baby is 11 weeks and I totally adore him. Its other people lol. Anyone else find this with the mini pill and how long it take to pass?
