A BABY now! Too early?

Caroline • Food nerd!!!
Started having sex for the first time a few months back
​My SO whom we're 3months old in the relationship  released his seed inside for the first time, and we talked about my chances of getting pregnant and he said he wouldn't mind if I do get pregnant for him
​Just turned 24 and he'll be 26,we have plans of getting married but I want to take my time, we both have a lot to achieve and we had a quarrel over me taking a morning after pill(which I actually did take behind him)
​I think it's insecurity because I'll be away for 1year and he's worried
