when did you start noticing weightloss

I am only down 5 pounds and usually when I lose any kind of weight I can start to see it in my face first. I am not trying to rush my weightloss because I did not gain it all in one day. I have been walking 4 times a week for 40 mins and doing some light exercises at home. walking now is much easier than it was a month ago but when I look in the mirror I still see the same person I was a month ago. I haven't measured myself which I know I should. I would just like to know when did you all start to see the weight loss? how many pounds was it before you noticed? im usually one to give up but I don't want this to be a reason why. I am almost 30 days strong. I just hope to see some kind of result from this
