I take 4000 mg of pharmaceutical grade fish oil every day, before during and after pregnancy. It has many benefits but the specific early benefit is that in high doses it can help regulate and lower NK cells. Later it is good for brain development, also is supposed to help with depression (there are clinical studies for all these issues).
Pretty similar to this except not pharm grade (pg, children)

I bought a high quality molecularly distilled brand - before and early on I chose high EPA for the modulation of NK cells and then switched to a high DHA one for their brain development. Continued when they arrived at 25w6d and pumped breast milk for them. Despite average IQ for micropreemies being somewhat lower than term babies, I am blessed with very bright little ones, and think the fish oil was one of the things that made a difference in their development.
Eating fish (certain types, there are lists) is considered bad for pregnancy unfortunately because of high mercury content. Even farm-raised versions of these fish are bad, because their feed consists of processed fish high in mercury. You have to study carefully to see which fish are OK. The OBs usually restrict these fish portions to once a week. I just gave it up entirely.
Cheap fish oil is crap, has too many impurities, not enough EPA and DHA to help you anyway, and possibly contains mercury since it is not really regulated by anyone. You would never want to take it in high doses.
The good fish oil that is supposedly regulated for purity is expensive, much more potent than the cheap ones though because it has been refined, and needs to be taken in high doses to have effect, per the studies. "High dose" is 4 or 5 capsules per day (4000-5000 mg).
