I've been on the pill for years (barring pregnancy) and apart from Cerazette have always had withdrawal bleeds. These packed up in January, leading to ovarian scans and cancer tests, which thankfully were all clear. My regular GP was convinced that it was down to the pill itself, the gynae specialist GP in the practice thought it more likely that thyroid hormone imbalances were the cause. While this was going on my fT3 was low, but just in range.
Well, the withdrawal bleeds came back yesterday. Here's the question: is it more likely to be because I've found the right thyroid med combo (currently on 150mcg T4 and 6.25mcg T3 / day) or because I've started supplementing with magnesium, selenium and zinc? Probably the former but I'd be interested to hear of other's experiences.
Could this be a useful future marker of my fT3 status?
