Looking for feedback.

Hello, I’m a Trauma-informed mind body coach and I’ve developed a group program with a naturopathic doctor, Bouncing Back Better from Baby Brain. Our offer is helping mothers to get back easier from postpartum. I’ve done Facebook ads, posting on social media. No clients signed up yet the program starts on 8 of March. We started like 2 months ago, not many feedback, just from friends and they said it’s so good. The program is for 5 weeks and the price is 1199$ per person and the limit in the group is 20 people. There is 1:1 coaching and access to a naturopathic doctor and weekly meetings with different topics.

My question is I don’t know how to test, what is not working. The name, the message, the price. Can you give me some insights? Thank you
