Pull out method

My husband and I are definitely wanting to have another baby within the next year. Our daughter will be 18 months on the 2nd of May, We are going to a wedding tomorrow and will have a night to ourselves. We are out of condoms which we have been using but what if we just pulled out? we wanted to start trying in june but what if we just did the pull out method instead of condoms? do you think the odds are high i could get pregnant in the next couple months? what would y'all do? i know my husband will say he wants whatever i want and he said he is ready to have another baby so he's no help lol!
