I had a miscarriage in February (6 weeks)  last year and another one in the month of August (15 weeks) last year. We did all the possible tests like semen analysis, karyotyping test, male infertility panel etc and everything is normal except my thyroid it was 4.10 in March and the doctor increased thyroxin  dosage to 24mcg from 12 mcg. However, we did the thyroid test once again in April it is 4 .2 now. I am worried and still we haven't got the reason for miscarriage and now I am not conceiving. Need help 😞. How can I reduce my tsh.
