What to do when you find out your pregnant and have Hashimoto's?

One of the first things I thought of when I found out I am pregnant is testing my thyroid, but when? Should I wait till my OB appointment and discuss with him or call my endo? It was kind of hard to find an answer but I got a quick one here:  http://www.nytimes.com/ref/health/healthguide/esn-hypothyroidism-expert.html?pagewanted=all

Dr. Alex Stagnaro-Green says, "as soon as they get pregnant, I have my patients call me immediately to get thyroid function tests so that I can modify their dose as early as possible in the pregnancy. Bottom line is that as soon as a woman knows she is pregnant she should be tested and see her doctor."

Your thyroid functions differently with all the flucuations of hormones going on, so getting a blood test as soon as possible is important. 
I called my endo last week on Thursday and got the blood test requisition on Friday, 5/24. Being Memorial Day weekend, I waited till today, 5/28, to get the test and we should have results in the next few days
