I am 39F and I used to have monthly periods very much on time. But since last few months I am facing very irregular periods. As per past records, i got periods in 30, 35, 26, 32 and this month in 18 days. Please let me know if this is normal? Moreover I am having very much sleep disorder as well as unexpected weight gain in last 1 year. Although I am doing 1 hr exercise daily. I have
thyroid issue since last 11 yrs but it is under control and am taking 62.5 mcg daily. Please suggest.
