Anxiously waiting

My bf and I have been having a ton sex lol. We used a condom a couple of the times but one it slipped off completely. There was a small slip up one time where I didn't get off quick enough......so now I'm sitting around waiting to see if I miss my period. I have three kids from a previous marriage and he has two from his previous. That's already a lot of kids!! I'm kind of nervous but the good Lord knows I'd love to have his baby the plan was to do that after we got married. Ahhhh I'm so impatient.
