Confusion...trying to sort things out.

I'm struggling....this is the truth. I don't even know where to begin but I haven't been able to blog since mid February. I haven't known what to say or how to say what I'm dealing with.
Jeph and I are trying to have a baby...it's taking longer than expected to get pregnant. We are both in prayer, being obedient to God, doing everything on our side to get pregnant. Ultimately we know it's Gods timing...we are struggling to trust in that and just be content/patient.
We are really hurting and both trying to be strong...my heart is breaking. I don't know how much longer I can go through this. Every month...we try, we wait, and my stupid period comes. We cry, and question...this is not good for our emotional health.
We both know that without children we won't feel content and happy. We both want kids so bad it hurts. With my sister Krista having another baby in September and one of my sister in laws telling me they are gonna start trying soon...practically every friend pregnant...I feel like I'm going crazy!!!
I need mercy and grace from God!!!! Jephs heart is breaking so much too...I feel bad for him, he wants to have a few kids so much and if I can't give them to him I don't know what I'll do, what we'll do.
I know this all will work out in God's timing...but I don't know when or if or what God's timing is. I feel confused, sad, frustrated all the time and I'm sick of living like this. We just want to have 3 kids of our own, the sooner the better and for everything to work out well! Is that to much to ask?

Please God...please have mercy on Jeph and I. We desire to have a house full of kids and to love and serve you. Please God..give us your peace.
