Hyperthyroidism and pregnancy

Am in first trimester and have hyperthyroidism - during my last pregnancy is when I started to have hyperthyroidism (due to  toxic nodule - I do not have Grave's disease) but did not need to take meds and my lab result stabilized after I gave birth. Pregnant again and today's results:
TSH <0.01; T3 6.7; T4 2.1. I do feel terrible, mostly fatigue and PA stated I need to take PTU. Have researched this as seems to have possible birth defects plus read an article that should only take unless deemed necessary. I don't want to take this med while pregnant. Can anyone share any insight or experience will this med and if my results are showing that it is "necessary" to take this.

What are the reference ranges for the T3 and T4?  Ranges vary from lab to lab and have to come from your own report.

Also, are they Free T3 and Free T4 or are they Total T3 and Total T4?  They aren't the same tests and don't give the same information.

My research confirms that PTU can cause issues if taken during pregnancy.  You should talk to your ob/gyn and see what other options may be available, since hyperthyroidism is not good either.  

We'll be able to tell you more once we've seen the reference ranges for your labs and know if your T3 and T4 are Free or Totals.
