Is there anything different about starting GLP-1 medication in your 30s while also trying to have kids eventually?

The main consideration is the same regardless of exact age: GLP-1 medications aren't recommended during pregnancy and are generally advised to be stopped before actively trying to conceive, so timing treatment around family planning goals is worth discussing directly with a provider. Some people use a course of treatment before actively trying, given weight can affect fertility for some, while others prefer to wait, it's a personal timeline conversation with your provider rather than a fixed rule.
