Ovulate early while on Femera

Has anyone ovulated early while on Femera? I usually get my LH surge around CD 13-14 & I always surge at night for some reason. Last month, my doc told me to be sure to BD a couple of days before I go in to see her (Day 12 follicles check) just in case I ovulated early. Lo & behold, I actually did get my surge early this time (CD 10). But now I’m wondering what is the point in taking the trigger shot since I will, in fact, ovulate early. Of course I’ll be asking her this when I see her on Monday but in the meantime, I would love to hear from anyone that this has happened to.
