Anyone know of any innate remedies that can be taken to regulate period?

I haven't had a length since November, I'm not pregnant as I did a test this morning, my period have other been a bit irregular since stopping the pill a couple of years ago, I of late want to get my period regular again My doctor recommended evening primrose oil capsule and vitamin B complex. I never actually tried them as i concluded up having a coil fitted but could be worth checking out. Apparently they regulate hormones.
Chinese herbal shop would be capable of help or a strength shop. Ask there
