Hey, I had a section too.. Am now 10 weeks pp and only just able to get back in some pre-pregnancy clothes.. The first couple of weeks I just wanted to cry my stomach was awful.. Stretch marks everywhere, sticking out like I was still 5 months pregnant!! I honestly felt a bit like ET, and I'm only 20 so I kinda expected to "ping" back into shape as soon as I gave birth! That was rather silly looking back on it! We've had major abdominal surgery, it does take a few months to go back to some kind of normal..
I do recommend some firm control pants, like Bridget jones style big! They hold you in, make the wobbly area feel stronger and they made my stomach shrink back down to normal after about 2 weeks of wearing them.. I think the compression helps with the swelling..
Oh and as for stretch marks/discolouration I love Bio Oil.. I've been using it for a few weeks and my tummy is getting it's normal look back, I actually am starting to think that I might actually be able to wear a bikini in the future!! So yeah, tight granny pants and bio oil is the way to go!! x
