I assume that you have Hypo Thyroid
and irregular period. You were on Clomid
for 9 months for your ovulation problem. Discontinued for 4 months and you have missed your period.
Similarly you have not taken thyroid tab for 4 days. The results are showing normal results.
The results will not alter by just stopping the tab for 4 days.
For your regular periods you have to continue Clomid as well you have to continue Thyroid tabs regularly.
