I´d say avoid measuring. You can get different measurements on one single day, and you´ll get very frustrated if you don´t see an increase on tape. I think the best way to notice the difference is by using your hands, in the beginning you´ll feel more fulness and that´s always the first step in the right direction.
Another thing that tells you if you´ve grown is if someone else notices, in ths case your husband, so congrats on your progress!
