Can consider the following: 1) Flavoured fish oil (took this for #1) 2) Use flavoured drinks to mask the taste when taking the fish oil (did this for #2) 3) Switch to plant/vegetarian source of omega oils (personally not tried this so please do your own research/reading or check with your gynae)
I stop taking my fish oil, instead i eat avocado once a day or 3x a week and salmon twice a week
