Yall.. cant shake extra pounds

So I had a baby 15 months ago. I'm still currently breastfeeding. Well my ring doesnt fit, still... really debating on getting it resized even though I told my sister to wait wait wait dont get it resized... it took her about a year til she could finally wear hers again.. now it's over a year for me. I'm wondering if breastfeeding is what is making me hold on to these chubby little fingers or if it's just how they are now... to me they look like water retention not necessarily growth or fat... idk I've lost most weight everywhere else... just kind of at a loss. Just wanna wear my ring again.. but I'm so weird about it being altered dont wanna weaken it.. so what do you think? Anyone ever been in this boat?
