I'm a vegetarian so can't comment much on the fish oil thing... but I think omega oils can possibly help. I was taking (and I am again) flaxseed oil capsules for my omega but the month before getting pregnant I switched to Udo's Choice oil. This is a very well formulated omega oil you can buy from health food stores. I'm really not sure if it made a difference to conception but it had been recommended to me by a friend who swears it is the secret to getting everything going and aiding conception
