I am 8 weeks pregnant and I am so jumpy...cooking dinner and my partner came through door to see me and I jumped out my skin....plus the dog barked...as he usually always does at people walking past the house...I was scared out my mind for a moment...even when the house phone rings I swear ile have jumped and hit my head on the ceiling...what is wrong with me? I had 2 children before and I do not remember being like this
