Detailed Answer:
Hello,
Thanks for trusting hcm about your health care.
I have gone through your history and understand your concerns.
Yes,50mg of PTU is safe during first trimester of pregnancy but in second and third trimester she has to switch to methimazole tablets( these are more safe drugs).
Emigo can be taken during pregnancy to control vomiting but if you are unable to have anything after medicine, you should consult your treating doctor and get intravenous infusion and iv medication.
Weight loss can be due to hyperthyroidism also.
Hope found useful, feel free to ask more information.
Good luck.
Regards
