Delusional about my weight??

Alejandra
OK so I will take the risk of sounding like a complete fool. I see a few ladies on here say "I haven't gained any weight but I was a little over weight before baby" OK so my question is how did you determine this like did your doctor say so or are you going by some specific chart or anything because I'm 5'7 and 180 lbs if you look at a chart on line or anything it says I'm over weight but either I'm blind and delusional to my own weight or those charts are insane my doctor hasn't mentioned anything about my weight and I haven't gained 1 lb I know it normal still at 17+4 but to think it's because I was already over weight seems weird to me. Below is a not very good picture of me before I found out I was pregnant
