Cleanse before iui

Af is due in 16 days (although she will show in her own time...) I'm thinking of starting a 10 day cleanse (from advocare)a week from tomorrow. Has anyone done a cleanse before iui? Or anyone think it would be a good idea? I have recently lost 12 pounds (my RE recommend loosing some weight to boost my fertility)and I'm thinking this clense can boost my weight loss and fertility.
