I am reading Parsley tea works. WHEN do I start this. and how much tea do i need to drink. should i drink it daily for a month before? I ended my period 2 days ago and I am having a cup a day. is this wrong? should i have 4 cups for a week prior? I have a cruise and i dont' want my period on day one....so I am hoping to bring it on a few days early. please help.
