odd weight question...

So I started at 157, I now am 190.
I'm 5'4 so icstarted considered "over weight" 
I'm mostly all belly but can see some weight gain in my face a lot and some in my arms. 
BUT mostly in my back/sides and my stomach even sags for being a pregnant belly?? 
Anyway, did anyone else have this and still lose weight after baby? 
I'm scared my stomach will just sag and I'll have huge sides/love handles and a bunch of back fat after this. 
I know it's part of it but I would like to get back down to what I was atleast to fit in my clothes and want my body to naturally slim down some.
I do plan to breastfeed . 
Any tips anyone would have also?
