Lost less weight but a lot of Centimeter

Ive been struggling with my weight almost all of my life
My highest weight was about 80 kg at the age of 19.
At that point i had enough and lost about 10 kg.
I kept that weight until i got pregnant and gained 16 kg during pregnancy :S
So 1 month after the pregnancy i was about 86 kg ;(
That was in 2010.
I didn´t really made an effort to loose weight and got down to 75 kg.
But i did look horrible at that weight!

So i started weight watchers and lost 13 kg.
I gained a lot of it back cause i wasnt able to sustain the my weight :S
At the end of 2012 i decided that i gained way too much back and that i have to start over again.

I lost only about 3.5 kg since than but i lost a lot of cm
