when i was pregnant with my daughter i was told i had hypothroidism and was put on synthoid,well soon after that i was told my baby had a heart murmur but then she was fine,well i quit the medicine after i had her because i started having bad panic attacks,well in jan 2010 i found out i was pregnant again and i told my doctor about the tyroid problem and they did not check my levels and just gave me the synthoid,well about 2 weeks later i miscarried,the babys heart just kept getting slower and then at 9 weeks it died,and once again i was having really bad panic attacks again,so once again i have quit taking it and i just found out i am pregnant again,well im scared im going to miscarry again,should i take the synthoid or is that what caused the miscarriage?is it possible that i dont have hypothroidism and the synthoid is not needed or do i really need it and thats why i miscarried? any help will be alot of help
