I think I got my winner already from my parents who were visiting. This morning in the car, my dad said something was odd and the wording didn't even sound like him (older Chinese man).
Dad: "The last three months, you need to decrease your sexual activity"
me: "What? Can you repeat that?" (I was sure I misheard).
Dad: "The last three months, you need to decrease your sexual activity. It may cause a miscarriage. Don't forget to tell your DH. Someone needs to control it."
