Letting Go

Are you a control freak?
I am in a way...I like to know when and how things are going to happen. I prefer to have things planned out and organized. Now, vacations are a different subject altogether b/c I prefer to not have plans and do whatever we want at the moment.
Fertility for me is such an unknown (having a few reasons but not knowing exactly why I don't get pregnant) and God has taught me something with each time. I must be a bit stubborn and/or hard-headed because a few lessons it seems I have to re-learn.
The main one being that I need to let go of my will and trust Him and His plan for our family. I am so very excited to be pregnant and to not have had to wait the years we have waited before is wonderful! This has happened much quicker than I could have dreamed. Praises to God for that!
But, I am struggling with being cautiously excited and not wanting to trust that God has this. I know deep down that I do trust Him and know that whatever is best for our family will come to be in His time. Maybe that is the hard part. Trusting that His timing and will are better than mine. Surrendering total control. Not that I can do anything about it anyways other than taking my meds and my hubby administering the shots. But letting Him have control and feeling it in my heart.
I am still having the same symptoms and they got even stronger as yesterday progressed. How do I keep from worrying and becoming distracted with am I still pregnant? I don't go back until Monday for additional bloodwork which gives me 5 1/2 more days to worry. I have a family to tend to and a job to do.
This is just such a roller coaster of emotions.
How do you handle giving things over to God? I am praying and talking to God constantly throughout my day. I know He has this baby in His hands.
I know I will learn something big and grow closer to God through this as I learn to let go and lean on Him more.
