CD 11 Monitoring Appointment

I went to the RE today.  My lovely mother was nice enough to play chauffeur for me, as I worked last night and didn't think it advisable to drive a 4 hour round trip on no sleep.  I expected they'd to the ultrasound and tell me I needed to come back tomorrow or Friday to check again.  Imagine how surprised I was when I immediately saw a big, fat follie on my right ovary and the tech said, "That one's ready to go!"  Of course, my left ovary decided it was going to be it's stupid self and play hard to get.  It hurts like you wouldn't believe when they ultrasound that thing!  Wowzers!  Anyway, there's a 13mm one on that ovary that I am praying decides to grow in the next day or so and also release.  Last cycle (the cycle we got pregnant with blackberry), I had one on each ovary, so only having one kind of worries me, but I know it's all under control.  The nurse talked to the RE who said I should trigger tonight and...ahem...plan accordingly.  I was shocked!  It was cd 14 last time before I was even ready to trigger, so the 3 day difference is puzzling to me.  Hopefully, all will be well.
