Injection time!

At the moment I am drinking a little hard cider to take the edge off my nerves as I get ready to do my first injection! I should back up a little first: last Sat. I had my day 3 appt. for bloodwork and ultrasound to start the cycle. Sadly, it was the day after my Grandpa passed away, and I was headed straight from the appt. to Michigan to be with my family. At the time they found a really large follicle or something leftover from the previous cycle, and when they called later with the bloodwork results, they said my estradial level was really high. Rather than start the clomid, I was to wait and come back on Thursday (today) and see where things stood. Today they found the follicle to still be super large, and my estradial level still high, so to try and "release" this follicle, I have a shot I need to give myself in my belly! It's usually called a trigger shot and used to "trigger" ovulation, but in this case I guess it is supposed to trigger the end to this follicle and allow it to diminish. The nurse explained very clearly how to do this, but now that I am home alone and need to do it, it's a little intimidating! But here goes! After this, I go back again next Thursday.... I have no idea if this means this cycle is out or if my next period should come sooner now, but will found it more in a week I guess. Wish me luck!
