I have been trying to conceive since past 6 months, I am aware when to try, what are the best days, I monitored everything but it never happened have missed periods this month, 4 days up of my expected period. Free beta hcg test I did but it came negative tsh was 7.8 so in january I started with 25 mcg thyronorm, now it's showing 4.5 (tsh) kindly suggest, what to do now, I am going mad why can't I conceive.
