Weight gain after birth???

Can somebody relate? Or am I the only one passing through the opposite weight gain thing?

My pregnancy weight was fine .... my face arms and legs kept the same only belly changed..... once I gave birth I lost the belly weight and extra water the first 2 weeks.... after that OMG I’ve gain 12 pounds already! I’m 5 months PP.... and I know that after giving birth it have been hard to eat as I just grab what is in front of me .....it’s just annoying ... don’t feel good to take pictures with my baby :(
