Hi there. Ever since I had my son nearly 6 months ago I've had constant bleeding. Long story short I'm now on levothyroxine for an underactive thyroid and it may be the cause of the bleeding. I am currently on desogesterol pill which I was on fine before I was pregnant for years. Doctor has suggested changing my pill to microgynon combined pill instead to stop the bleeding. He said I could either do the pills then take the break or take the pills consistently back to back for 3 months then take the 7 day ones. Can anyone help?
