Hi, I was taking 2 grains S.R. thyroid medication and ran out, and didn't get the prescription refilled (got caught up with life, didnt see it as a big deal). Well, literally when I ran out, I got pregnant. I am about 5 weeks pregnant and went to my doctor and he said I needed to get back on the thyroid immediately, and that he might need to increase it. My question is... have I already harmed my child by being off of my thyroid medication for the first 5 weeks of pregnancy? Obviously I intend on being vigilant about it now that I know how important it is.
