Just wondering how long it took teens to regulate if you don't mind. My dd is 13, started at 10y8m and still random each month. For the first couple of years it was anything from 14-42 days - nightmare for her! Since September, 21-33 so a bit more predictable and "normal" according to NHS website. Do you think this is her now given it's been over 2.5 years which seems to be what Dr Google says is how long it takes for cycles to regulate?
