TSH of 0.87 is on the lower side but still falls within the range considered normal for the second trimester, since pregnancy hormones naturally push TSH down a bit. Your T4 of 12.08 also reads as a reasonable value for this stage, so these numbers don't point to a

Trimester-specific reference ranges vary slightly between labs, so ask your obstetrician to confirm these results against the range your lab uses for pregnancy.
