Iwas diagnosed with an underactive thyroid when pregnant with DS2 2 years ago and have been on medication since then. I have been TTC since December but no luck. Since last July my period has been up the left - 25 day cycle instead of usual 28. Last cycle was 32 days (was convinced I was pregnant 
).
Has anyone else experience this problem or am I starting the menopause (only 39 
)?
