And so it begins again

This summer I learned quite a bit about myself. I learned that I am stronger than I thought I was. I learned that it really is okay to Let go and let God. And when you do that, prayers are more often answered. I have learned that I am powerless over my emotions and I need help dealing with them.
I turned to God after my second miscarriage. I leaned on Him like never before. I found that the more I gave it all to Him, the calmer and happier and at peace I was...so much so that after dinner one evening with my best friend, she texted me that I seem like a different person. That my whole "vibe" was different and that I seemed happier. I owe all of this to God!
My doctor has recommended that we start trying to conceive again right away. The odds are better in the first three months after a pregnancy loss. So, I have taken the fertility meds prescribed to me, along with some extra "goodies" he had ordered for me. Now, the much anticipated progress ultrasound is less than 36 hours away. This will let us know if my follicles have developed enough to trigger ovulation and proceed with IUI.
Here is the problem...I am reverting back to my old ways. I am worried sick that something will go wrong. In my mind, I HAVE TO have the IUI performed Friday morning because I have pretty important plans for the weekend. I LITERALLY cannot get the procedure done on Saturday or Sunday without ruining my weekend. The control freak, worry wart is in full effect and it pains me. I KNOW now what it is like to be calm and not stress over things I have no control over.
This should be something that I could just give to God, but I can't! The devil is playing a nasty game with my psyche this week and planting seeds of doubt.
So, if there is anyone who reads this please do me a huge favor and pray for me the next few days. I am going to need all the prayers I can get.
