Hi! So we are pregnant. We have been together for about 12 years and married since May. We had our first doc appointment yesterday. The sonogram thing showed that the baby may be smaller than it should be. It is only 6X10 cm and the doctor said it should be bigger. We think we are around 6 weeks. But when I used a pregnancy wheel app thing we may be closer to 8. I think the doctor realizes this and wants us to come in next week to recheck to see if more development happens. There could be a couple things going on. Our dates are off a bit and we are not as far along as we thought making everything ok. Or the little fella isn't growing as it should be.

Here's where I need the help. How do I help my wife? What do I even say? We are just not taught in life what to do in these situations. 

A little bit about my wife...

She is very smart. She is a worrier. She has a plan, always. She can not stand not being in control of something. She does fine when problems arise that she can figure out a solution and fix it. I think she is having problems because she k ows there is just nothing she can do except for what and see what happens. 

I am trying very hard to be comforting and calming for her. To let her know that everything will work out ok one way or another. She told me this morning that she wish she could be as strong as me but I'm really just trying to hold my shit together to be here for her. So, does anyone have experience with this type of situation? As a husband what can I do or say if the worst happens and we lose the baby? I realize that we are not there yet but I just want to make sure if something happens I am able to be there to support her. We both want this so badly. She told me this morning that she just feels like it's not going to be ok and that she feels so bad because she felt attached to it already. 

Any advice from moms or dads will be greatly appreciated. Thank you.
<bot>: Baby isn't growing as fast as it should be within the first trimester. How do I support my wife if things go bad.
