HI, Welcome to HCM
Firstly,
Folic acid and
thyroxine are two different drugs doing different work on body.
IF you have
hypothyroidism then it will hamper your
fertility. SO you have to take thyroxine for neutralizing the hypothyroidism.
Now, Folic acid is required to maintain a high rate of cell division during
pregnancy , and it also prevent any abnormality occuring due low cell division rate.
So, you have to take folic acid to have a normal pregnancy.
These two drugs are not related with each other and they will be taken simultaneously to have a pregnancy.
Now, if you miss your period , then you have to do a pregnancy test.
So, take folic acid as prescribed and it will not hamper IVF procedure.
Regards.
