❣why am I feeling like this ?? ❣

So I'm 10+5weeks pregnant an me an my husband did plan to get pregnant but now I am pregnant I don't feel happy like you would . I'm finding it hard to get excited an feel happy I'm just feeling relly scared as I've got a 3year old that's full on an I'm gonna have to have a c section again. My husband went out today an come back with a pack of baby bottles he had bought for him to get excited about the pregnancy. I have my first scan on the 22nd so hopefully I'll get on to it more then. I'm also scared that when I have baby I get baby blues...
