TSH blood test

Hi everyone,

I had done a blood test about two months ago when I had traveled in my home country for a myomectomy (removal of uterine fibroid). The test showed that I was borderline hypothyroid. After taking appropriate medication for a while my doctor asked me to stop the medicine for a few weeks and then do a test again to check if I was actually hypothyroid, so as to decide further course of action and try and get the levels to normal before I plan for a pregnancy. I am now back in the uk and went to my GP with my reports and get the blood test done. The GP told me that it was too early to do a blood test and that I should wait for 3 or 4 months before I get another blood test done. I have already stopped taking medication for three weeks now. Is it right to wait for another three months! by which time I would be very close to planning pregnancy since I was advised to wait for 6 months after the myomectomy
