Superstition

So I struggled with fertility for a year and a half. Girls in my family are very fertile. So I wondered why not me. I went to Arizona in late Febuary to visit my grandma. Who is huge into kokopelli and she gave me a necklace that was kokopelli. (Fertility God) she also knew a lady who did a reading on me with Taret cards and told me I was to be pregnant with a little boy. I had never met this lady before the reading and I am not extremely close with my grandma to tell her of my issue. So anyway I wore my necklace everyday and in April I was surprised to find out I was actually pregnant! Then at my 20 weeks I was told it was without a doubt a boy! I can't help but think back if it was a coincidence or not. But I am scared to remove the necklace for fear I will lose my child. I have 9 days left. Am I just being crazy?
