When AF arrives uninvited

Jamie • Happily married for 4 years. Pregnant again after 2 Miscarriages and IVF #2!❤️
What are some things you do once AF arrives that you didn't feel are safe during your TWW, "just in case" time frame? Yes, AF came by for the Easter weekend totally uninvited. I'm just trying to stay positive 
So far I have:
Take a hot bath
Drink as much coffee as I want😝
Eat sushi
Eat raw cookie dough
Exercise as vigorously as I want
Cut calories as much as I want (to make up for all of that cookie dough, of course!)
If I get a headache I can take ibuprofen instead of crappy Tylenol
Hope you ladies had better luck than me this month
