I haven’t bled in almost 2 months, but I have really irregular bleeding anyways. I keep feeling like my bleeding/period is starting but there’s no blood… just discharge. What could be causing this or lack of bleeding for so long… I’m on the pill but haven’t ever gone this long without bleeding. Last time was July for about 12 days

One of the ways the pill works is by thinning the uterine lining, meaning there can be little to nothing to shed. Otherwise you don't have a cycle anymore, and bleeding is just a side effect of the pill and can either not occur at all or happen whenever. It's normal.
