I feel so ungrateful

Susan
I just a test and its positive,now we been trying for 6 months that got to a point where I was thinking about getting on birth control,my kids are 3(almost4) and 5(almost6) they are 2 yrs and 1 month apart,so I thought you know what maybe I am ok with just this 2,kids are expensive,now I feel guilty to the fact that I don't feel excited or too happy about it,I am scared,😔😏
