I found out I was pregnant 2 days ago!

I really scared too tell my mum and dad because they are currently paying alot off money for me and my son to go florida with them in April but because I'm pregnant now I won't be able too do rides and swim with dolphins. my mum has already said if I get pregnant she will not talk too me and apparently I will be selfish. what should I do?
