i was wondering if after thyroid removal will it be hard to conceive?

i heard stories that is dangerous to conceive if tsh is very low.I had doctors telling me that i can get pregnant and thyroid has nothing to do with it.

is levothyroxine or abnormal thyroid levels make it difficult to conceive?And what about miscarriages?can low or high tsh cause them?

Joannagof,

It is high TSH which can make it hard to conceive and increases the risk of miscarriage. British Throid Association recommends the TSH of women planning conception should be in the low-normal range 0.4 - 2.5 and that Levothyroxine dose should be increased by 25-50mcg when pregnancy is confirmed to ensure good foetal development.
