my period began to regulate itself when i was around a year clean off sub., i think all opiates can do that
Suboxone has 'buprenorphine', an opiate that has been around for 30 years with partial agonist activity. The effects are pretty consistent with other opiate effects; the effects on cravings are caused partially by taking it at a very high dose, which is the case with Suboxone. I have not seen effects on the menstrual cycle beyond cases like yours, where you never know for certain which med is at fault, or if none are, and instead the person has a hormonal imbalance of some sort. I recommend you ask your GYN to work it up, and try to keep the doc from blaming the Suboxone.
In general, docs and patients tend to blame a med for side effects if they feel guilty or uncomfortable about the med... in your case, I would probably suspect the SSRI before the opiate. But polycystic ovaries is probably more likely than effects from ANY of the medications.
