Is sea salt better for u during pregnancy than regular salt. does it have the same negative result if you consume to much?

Salt is salt: Your body doesn't really care where salt comes from. There is no meaningful difference. Salt in reasonable quantities is not particularly dangerous in pregnancy but can lead to more swelling of the ankles and feet, a common pregnancy-related problem, and is a problem if you have high blood pressure.

Not that I know of: There is no literature that I know of that supports the use of sea salt over regular salt in pregnancy. A quick search of various medical sources didn't find anything that is evidence based in that regard. Hope this helps.
