TTC after only using withdrawal method

Hello! My SO and I have been together almost 5 years. During that time, we have only ever used the "pull out method" and I have never ended up pregnant. This is our first cycle TTC and I feel awful because I know it should be a super exciting time, and it is, but I can't help but worry that something is wrong already because I read so much about how the withdrawal method is not effective at all. I had also TTC in a previous relationship with no luck, but I am fully okay with that one not happening. Anyone else have similar situations and end up pregnant?
