that would be me
As long as you take your medicine (which you are suppose to do while pregnant) youll be fine. I know that one of my big worries in the beginning was miscarriage because of it. To be honest, i ran out of medicine for three weeks and couldnt get more and the baby was still fine. Im now 34 weeks pregnant and have a perfect pregnancy. The only thing i would tell you to look out for is weight gain, because it is so easy to do, especially with the thyriod issues. Like i said just make sure your meds are right, tell your obgyn and she'll test your levels to make sure they remain normal throughout your pregnancy because i have heard that they can jump all over the place ( mine hasnt changed but i have heard of cases where it has)
the biggest thing is try not to worry and enjoy being pregnant as much as possible!
as far as taking your medicine.. that can be rough in the first trimester because with mine at least i have to take in an hour before i eat. just do the best you can ( sometimes with the morning sickness its rough) i found if i either ate something and then took it out 2 hours after or just work up early took it and went back to sleep right away it was best.
