Feeling sad

So everyone around me seems to be pregnant and I also work at a daycare my boyfriend and I don't use protection and we aren't having any luck and my period is a week late but last month it was 22 days late so I'm so confused as to what's going on kinda really want a baby but doesn't seem like it's happening I worry because my mom got cerival cancer at my age and couldn't have any more kids so I get scared that it might happen to me and my boyfriend says he's not fertile lol
