Please help

Hi everyone! I'm 19 and have been ttc baby number 1 with PCOS... I was put on metformin (1500mg daily) about 2 months ago and still no sign of AF I've decided to take Maca with this and EPO (evening primrose) and see how I go, any thoughts about this mix? I'm also thinking that when AF shows I should try Promensil (isoflavones) has anyone had any luck with this at all??? Or does anyone know if any of them interact badly at all? I'm also currently on antidepressants... (Effexor 100mg) please comment!!!
