nervous excited scared happy

Sarah
I just had to let this out 
I'm sooo excited that we're pregnant...but I'm so nervous that I could miscarry and all day I have these mixed feelings! Every time I go to the bathroom I'm nervous that I may see something that I shouldn't ..I don't even know if this is normal. 
I'm sure stressing. About it is even worse
Anyone that has gone threw this when does it stop..the worry and all that..
