Bleeding mid cycle irregular cycle need help. any advice?

Faith

I came off birth control in July...I’ve had irregular periods since not my 28 day cycle as it would have been before my last period came in 28 day cycle although previously they haven’t. I had spotting start cycle days 14-20 very very light to heavier but not heavy like a period no other symptoms. Friday and Saturday pink cm and sat light streak of blood. Shooting pains in breast and mild cramping a day Stratford before the spotting stopped a day after on Sunday if under 28 day cycle I’d get my period today nothing but clear CM I usually get at midnight. Any thoughts ladies? Need advice not knowing is making me crazy. Negative test with one line thought faint but I guess it’s evap read after time frame and runny dye.
