How are you calculating your ovulation date after a trigger shot?

Elle

I just found out I’m pregnant from my third round of Clomid. I had a mid cycle scan on CD 11 and my nurse triggered me at the appointment. I don’t know if I should estimate my due date from my LMP or an estimated date of conception. If I use the estimated date of conception, what CD should I use?

I know I’ll get all of this info from my doctors office but they won’t schedule my first appointment yet!

Thanks!
