You and the baby should be perfectly fine and as long as you are now taking 1000 mcg a day, the development of the fetus should go great.
At this point, you should be going along great and now it is time to stop worrying and get into being pregnant. This is your time and everyone should be taking great care of you now.
Just don't forget to take your vitamins and if you want to take a little something extra, enfamil now has a supplement of dha/ara that is not fish based that can support brain and cns development.
good luck and congratulations, its time to party with virgin daquris and lots of whipped cream!
