I am having hypothyrodism and on thyroxineI00mg od (TFT under normal )and had an irregular periods . I menstruate once in 42 days . I am planning for pregnancy last 5 months. Two weeks back i went to hospital for bleeding it longs 14 days and as per Dr advice i took Tab primolut -n 10mg for 8days. After starting primolut, bleeding stopped and we checked ovulation in home by urine test and it shows positive twice.After 3 days of discontinuation of primolut i start bleeding and today is second day and second day bleeding is heavier and contain clots .Is it normal ? Is there any chance to have pregnancy now ?
