Naturemade prenatals has mackerel?!

So I’m looking at the label of my prenatal and notice that it’s source of fish for the fish is anchovies, sardines, and mackerel! Aren’t we supposed to stay away from that fish during pregnancy because of potentially high amount of mercury?!

Why oh WHY would they put it in a prenatal that’s FOR pregnancy?!

Did anyone use this and find out that it’s still safe or ok?

I’m almost 8weeks, so idk if I should switch or not..
