Should I get pregnant???

Hi everyone. 
​So me and my husband are officially going to try and get pregnent this Christmas time. 
​But we are currently just using sex not on ovulation days so we know we have a chance it could happen.
​I want to start trying tonight and it's my fertile day should I just have sex tonight and see what happens?
​We would be happy what ever way. It's just hes thinking we are trying in December. What would you all do???
