Thanks for the info. The Primrose definitely took my period away. I've been regular for 2 years now and this has been the only month I've missed. Maybe I just started it at the wrong time of my cycle or something. (probably around ovulation)
I'm just going to finish the bottle of this primrose and see if anything happens. If not, then I just won't take it again and look into the chasteberry or maybe just live with the breast pain. I'm sorta upset that the primrose got me all off schedule, but I guess it goes to show that some herbs are more potent than you think they are.
