Bindy it is perfectly safe to take fish oil throughout your pregnancy. Yes, it does seem like a high dose but it's fine. There are benefits to both you and your baby.

In our culture we are often lacking omega 3's as we do limit fish intake during pregnancy due to the worry of mercury contamination.

Flaxseed oil is contraindicated in pregnancy as it has an anti estrogenic effect. It is actually often recommended not to be taken in the second half of your menstrual cycle when TTC for this reason.
Thanks Flowerchild, will go and get a new bottle tomorrow....
