2 months late

Basically, I was late picking up my prescription (yaz - combo pill) awhile ago so I skipped my pills for that month. I was told to start taking them the first day of my cycle when I started them last year and I was beyond that point this time so I decided to just restart them the following month... but my period hasn't came back. I've technically skipped 2 cycles now. Is this normal? All pregnancy tests have been negative plus my husband had a confirmed successful vasectomy years ago so pregnancy is slim to none lol. I take the pill for acne and would love for my cycle to come back so I can get my skin back in order. I've never had this happen going off the pill in the past. No more stress than usual and no other changes health wise.
