MTHFR pregnancy?

Jessica
Hello all - my husband and I are trying to learn more about MTHFR and pregnancy in order to decide if we should move forward with either trying to conceive naturally or adopt. I'm a heterozygous MTHFR carrier and have hypothyroidism. We haven't been actively trying to conceive yet but have been tracking  bbt and taking ovulation tests with mixed results. Any mamas out there a heterozygous MTHFR carrier? Was pregnancy difficult? Did you have to take extra precautions during pregnancy to carry the baby to term?
