I stopped spironolactone 3 weeks ago as it caused breakthrough bleeding. How long will it take for hormones to normalize?

My sister (a dermatologist) put me on spiro 150mg/daily back in January. About 2 months later i started having breakthrough bleeding, especially after sex during 2nd half of cycle. Cleared for STI's and pap, very healthy. My body is very sensitive to hormones. My gyn said i have cervical ectropian(often caused by oral cont or anything that increases estrogen). I stopped spiro 3- weeks ago ...how long for hormones to normalize? Would it take months since it takes months to work? 4
