Period late one month. Will it be late the next?

Okay so last month my period was about 2 weeks late. It came on May 23rd and now its Monday, June 27th and haven't got it yet but i will be going on vacation this weekend. So it would be handy if my period came 2 weeks late again because i will be going to the beach and swimming and I'm 14 so i wouldn't like to wear tampons. So i want to know if it's most likely to come late again this month.
