On 9th Aug, I delivered a baby through c section. I have hyperthyroidism and was on medication on 125 mg before delivery. 2 days before tsh test was done and the level was 0.06 so what medication should I start now because I also breastfeed my baby. And from few days my breast milk is also very low so I am taking lactare granules powder and lactare tablets for this Please suggest thyroid medication.
