Lost baby weight

Asia • In pursuit of our Ancestors...
I suffered a miscarriage with my last pregnancy i was a good distance along and it showed in my tummy... my body never bounced back...today my SO mentioned I could be in better shape. I had a bit of anxiety from it... here I am TTCing hoping to get fat and pregnant... when I should be getting slim and trim... should I stop TTCing and focus on a beach body instead?
