Sometimes BF is not the weightloss wonder that it is assumed to be. As we gain weight during pg, our body lays down fat stores to prepare us for BF and sometimes our bodies need to hang on to that weight to be able to produce milk. I know how frustrating it is not being able to fit into anything, but there is a saying that it takes 9 months to put the weight on and it can take 9 months for it to come of again.

Another thing is you might be eating too healthy and excercising too much, sending your body into 'flight or fight', meaning that your body thinks tht this aint right and is holding onto the weight so you still have milk. There are many reasons why, and it will be different for every woman. Plus bubs is only 9 weeks old, give it a little more time.
