Question RE: 1st Ultrasound !??

When did you ladies have your first ultrasound (Canada)
​Should you have an earlier one then the traditional 12 week one if you've had a miscarriage?
​I've had one 3 months prior to becoming pregnant again, and a bit concerned about waiting until 12 weeks (doctors recommendations) as I experienced a Missed Miscarriage the last time. I've learned that insurance only covers 3, so if I request an earlier one will I need to pay upfront? 
​What is your experience with this?
