The Closer It Get, The More Scared I get!

I was hoping to come across some other women the felt the same as I do. At first I started out excited about FINALLY having a girl after 2 boys and couldn't wait to feel her kick and see my belly grow and go shopping for PINK! And the past like 3-4 days every time I look at my belly or feel her move or even hear someone talking about babies on t.v. I want to vomit and curl in a ball and cry! I literally get this gut wrenching sick feeling. And idk wtf to do about it bc I have 4 outfits for her and NoTHING else! If this doesn't go away Idk if I will even be able to go shop for her stuff bc I just want to lay in bed and hide and cry! I also have an almost 4yr old and a 9month old. My hubby thinks that all the stress I have been feeling bc of hormones and having a hard time handling them at times has me freaking out. But I honestly dont know. I just need some advice. And I NEED to know I'm not alone
