Pull out method

Help!! I've been on contraception for over 10 years. Started off with the implanon for 6 year then the pill. I decided to get off all types of contraception because I'm so scared that it will effect my fertility. My boyfriend and I have been using the pull out method because we're not ready for a baby just yet. I'm so worried though that I will fall pregnant. I feel like I'm torn. I don't want a baby yet but I don't want to be on contraception anymore. And I can't stand condoms. What are my actual chances of falling pregnant using the pull out method?? My boyfriend is really good and is able to control himself. But what about pre cum?? Arrhhhghh so many questions !
