Advice please?

Okay! I got my BFP this morning and I'm the type of person who just LOVES telling everyone any good news the second I know but my fiance wants me to wait until the 3 month mark to tell everyone. I can't contain my happiness. When I was pregnant with our first we couldn't keep it a secret because when we went to parties like a typical Friday or Saturday night I refused to drink haha. Now with our daughter we don't go out and drink all the time. Secret can be kept but I'm about to burst. Should I plan a big I'm pregnant party to put my excitement into? How do I keep myself contained!!
