Hi, Does anyone know if having your period can knock you out of ketosis? I've been on New You for a fortnight. I've only eaten New You products and drunk coffee, peppermint tea and tap water. The ketostix were dark purple last week, and this week barely pink. Only thing different is I had my period over the weekend. Sorry to gross people out, but I can't think of anything else it could be. Any other suggestions gratefully received.
