Aaaaaaaaaaaarrrrrrrrghhhhhhh

I am trying not to obsess, but, it feels like a lot of time has passed since the clinic called me yesterday afternoon to say, "trigger tonight and IUI on Sunday." I feel like it is too late. I have forgotten the timing of it all. I am worried that I have ovulated already or surged before the trigger or ?? They are the clinic they should know, right? So probably the timing is right on, right?
