Well, I don't know about the adam's apple. I've never noticed it in any of your pictures.
Could be the extra weight is covering it, but more likely you're just being paranoid.
Because I really doubt 5lbs would do much, the first 5lbs would probably be lost in your stomach.
About the breasts - this is why many women's complaint about weight loss.
I mean they're mostly fat, so if the fat increases, they increase.
Mine would go down in size if I lost weight, but nah, me and thinness do not mix.

Also keep in mind that maybe your fat distribution hasn't really taken place yet.
When it does your face, neck, and breasts should fill out more.
