Nursing moms - when did your weight settle out after weaning

I’m on baby #2 with intolerances and got pregnant again within 2 months of weaning, so I’m not sure how much weight I’d gain after going back to eating an unrestricted diet, ie back to eating dairy, soy, and egg.

I’m hoping to finally buy new clothes and clean out my closet after I’m done breastfeeding but I fear that I’ll change sizes once I can eat whatever I want again. How long did it take your body to find a new norm after being done with breastfeeding and a restricted diet?

Side note, with my first baby with intolerances I went down a size. This baby I’m about the same was before kids. I don’t generally gain or lose weight very easily.
