TUNA - read question

How often can you eat tuna ?

I’ve had fish once this pregnancy (A little over 8 weeks) just does not sound good (I have been taking a quality DHA because of this)

Yesterday I ate a tuna sub and omg it was amazing.

I really want another one today. Is it okay ?

I highly doubt I’ll want it again after today since usually something that sounds amazing goes on to sound disgusting 😞
