Keeping it secret

I’m a teacher, 4 weeks along now and in 2 weeks time I have a week at school that will challenge my ability to keep the secret!

I have a massive day of parent-teacher interviews from 10am-8pm. 3 breaks across the day.

Then I also have a school camp for 3 days, 2 nights (in cabins with real facilities so not roughing it at all).

I have nausea now and I’m just praying that I won’t have it or other giveaways during that horrible week! I am sharing a cabin with 2 teacher friends who I can tell if I really need to. I plan on telling school in general when I get past 12 weeks.

Any tips to keep it under wraps?
