Penelope,
I am a lay person and not an expert, and my subject is omega six and three. Please discuss dietary change with your doctor.
Please see the greek diet and cox 2 posts, which contain the some information as to why.

It is ESSENTIAL to
balance the omega threes and sixes which means
cutting down on omega sixes, the highest sources of which are vegetable oils (excluding Virgin oil, flax and a little coconut and a few other exceptions - see nutrition data)

There is a range of opinions on how much long chain omega three, but many sites making medical recommendations suggest between 1 gram of DHA, to 2.7 grams DHA plus EPA. A trial suggested that uptake of DHA in women drops off at about 2 grams a day. Smaller amounts will help but my personal preference is for the higher end rather than say 200 mg a day.
It is also important to get some mother omega three found in vegetable sources of which flax is a high omega three source. You will have to read the posts and decide if you prefer flaxseed or oil. There is evidence flaxseed is beneficial but it is a topic of debate as some have concerns.
But as above do talk to your doctor as fish oil can case blood thinning etc.
