Anyone believe in the power of visualization?

Serious question.. I’ve heard that you should try and visualize the whole process of sperm meeting the egg and implanting etc.

As soon as ovulation happens and I get to the 2WW I’m so anxious and full of doubt.

I have been TTC for a while now and I feel like I have a huge mental block.

Is it possible negative thinking could be hurting my chances or do you think it is a load of rubbish and nature will do it’s thing regardless?
