How accuarate is a pendulum reading?

So I am in a transition stage of becoming non christian to worshiping my ancestors. So I had someone whom is a dear friend of mine and she used a pendulum. First my throat chakra was spinning counter clockwise, she unblocked it. (3days before this, I was Dx'd with PCOS) So she asked her pendulum if I would be able to conceive, carry child to full term, the gender of the child, and the time I will get pregnant. How accuarate is this? What are cheap ways to keep my chakras unblocked and rituals, or sayings that I can say, anything to bathe in, and or what can I put on my altar for fertility. I have been trying to conceive for a while now. Please help me out.
