Hi, I think you should continue to take your prescription as it is very important to keep your thyroid
levels strictly within normal range during Ist 12 weeks of pregnancy
is absolutely safe in pregnancy & you MUST take it, if, it is indicated. It may be harmful for your fetus if your levels are not properly controlled. So, don't hesitate & don't worry at all. Just continue your follow up with your obstetrician & endocrinologist
. Best of luck.
