My reproductive system is broken??

TTC six months. The longer I’ve been off birth control, the crazier my body gets. Last “normal” period was August. September was a three days of on/off dark brown spotting (no fresh blood). October period was 17 days late. BFN and negative blood test for pregnancy. Dark brown spotting began again today. Constant cramping since stopping the pill (and I’m talking cramping so badly it feels like I’m getting my period daily). Breasts leaking some months, horrible moodiness. Using OPKs, and ovulation is all over the place (in October peak ovulation was 33 days after last period). Doctor is ZERO help. Anyone else experience this? Any solutions? It only took us one month to conceive our first so I️ am majorly confused 🤷‍♀️
