Hi Marie, I'm on my 19th day and I still have thoughts going on while I meditated. Yesterday I could felt my center for the first time but not for longer. What I've been trying to do is wait. Be patience and eventually calm and stillness will come to you. The first days are hard to concentrate I still find it hard, but don't rush to get it and you'll. You can also watch the video from day 2, the one with the tips to meditate, like drink a glass of water or take a shower before start your session.
At least that's my experience.
Peace to you.
