Out of my cocntrol?

Still no word from Peter's family.
Two baby blessings at church (twins). They were short and sweet. The mom bore her testimony that she never thought she would be a mom of 7, but the Lord had a plan for her. This made me think of a conversation that I had with a friend yesterday. We went down to the mall to check out the new H&M (major disappointment, btw) and she brought up a conversation that she had with some girls from church a couple days before. She is worried that once she removes her IUD, she will struggle to get pregnant again (she already has two adorable little girls) but whatever happens, the Lord has a plan. I, of course, had to explain my point of view. I think the go-to response when somebody is TTC is "it's on the Lord's time" or "the Lord has a plan". Since I do not have any children yet, does that mean the Lord doesn't trust me with one of his own? Does that mean that He does not want me to be a mother? Does that mean that He wants me to struggle with everything that goes along with TTC? Does that mean that he wants a 16 year old girl to get pregnant and raise a baby even though she cannot support a baby? Does the Lord want her to be a mother more than me? I think not. Yes, I believe that He has a plan. On the other hand, i do not believe in predestination. The Lord allows us to go through hard times so that we can grow and stretch ourselves. There are laws on this earth that have consequences. For example, if you have sex, you have a chance of getting pregnant. If you are 16 and have sex, you have a chance of getting pregnant. Everybody knows this and we have our own free will to make the choice whether or not to have sex. There are also technologies out there that allow us to take fertility into our hands. Ultimately, God can make miracles happen. He can allow be to become pregnant, but some things we have to work for. We are saved by grace after all we can do. For some, there is not much work involved in becoming pregnant. For others like me, we have to work. Go to doctors appointments, get poked and prodded, and go through the excruciating pain just to try to fulfill a life-long dream of becoming a mother. Telling me it is on the Lord's time does not make me feel better, it is just lazy. It is easy to fall back on that excuse without thinking about our own choices.
That being said, I do believe that my Father in Heaven loves me and has a plan for me. If I knew that plan, there would be no need for faith. My faith has grown though this experience (although if it were over soon, that would be fabulous). I know that He knows me and my struggles. I know that my Savior has walked this path and is walking it with me. Sometimes, I feel like I am completely alone, but if I ask, I can feel His arms around me.
