I need someone to give me advice..

Paige
After almost a year of trying I'm finally pregnant.. I am so happy and filled with joy.. But I am stressing myself out about what if I lose it.. I am so nervous. My husband is in the military so the hospitals here are a little different.. They don't do ultrasounds till 20 weeks!!! That just blows my mind. I'm going to go to this safe 3D and 4Dplace called baby bump that will let me see and hear the heart beat at 8 weeks. As I'm calculating I'm probably about five weeks. I really haven't had any pregnant symptoms yet.. Except I do have really bad cramps every once in awhile. And I'm super picky about what foods I want now.. I have felt nauseated after I really want something to eat, then I'll get it and then it's nothing something I want. Lol but I just don't want to worry. I have taken two tests one in the morning and the second one in the middle of the day. So I know my hormones are pretty good for it to show other than just the first mornings urine.
