Tsh fluctuated 3, 04-6, 46 since 2008.last at 4, 85. t4free 1, 4. no antibodies. now planning for pregnancy. should i get treatment before conceiving?

Probably: Normal ranges for TSH vary but the american college of clinical endocrinology considers a TSH above 3 to be a sign of hypothyroidism. I advise checking free t3, (liothyronine) the most accurate measure of thyroid function. I find most with free t3's below 3.0 benefit from thyroid treatment. Low thyroid reduces chances of conception and increases miscarriage. See http://bit.Ly/16xtifq and http://abt.Cm/18gpb3a.
