Re: Pregnancy and Hypothyroidism
As long as your free T4 level is optimal... not merely adequate... you shouldn't have any more trouble with conception and pregnancy than the average healthy woman. For most women, optimal free T4 would be at least 50% of its lab range (median) up to about 70%. Lab ranges vary, but the typical ones would have 1.3 as median and about 1.5-1.6 as 70%.
Generally, for conception and successful pregnancy, TSH should be no higher than about 1.4 and free T4 should be in the upper part of its range.
Very, very high titers of TPO antibodies might pose a problem to pregnancy. If you have them, these can be reduced by up to 40% by taking a daily selenium supplement of 100-200 mcgs per day. I suspect that most prenatal vitamins contain selenium, but the label should be checked before adding a separate Se supplement to the daily regimen. You should not exceed 200 mcgs from all sources per day.
It strikes me odd that you see a doctor every 6 weeks for this after all this time in treatment. That's very atypical. If your levels seem right to you ... That is, if you feel well and have no thyroid-type symptoms ... They don't really need to be checked that often. Once or twice is year is sufficient, unless you have recurrent symptoms that can't be explained by other illnesses.
Good luck with your future plans!
