2 months post op Breast Augmentation. I feel like my hormone levels have changed. Can surgery cause changes in hormones?

I am experiencing the same sort of symptoms I did while breast feeding. Oily hair, acne and body odor. I am taking a mini pull for birth control and that has not changed. I also started getting my period again immediately after surgery as well. Since being on the mini pill I was never getting my period until post surgery. Thanks for your time.
