Thanks everyone! So nice to be able to talk and share about it! Will probably go with the antibiotic story, although I could do the 'fake beer' thing.
Wishing on a star, that's so funny, we told DH's mmum and my best friend too haha. We chose one person each.
Also nice to know I'm not the only one who has to pee every 5 minutes. I'm a swimming teacher so it's quite noticeable too lol.
