Am seeing GP re heavy periods. Have been using Tranexemic acid for a while. It works, but the GP I saw last time for repeat actually wants to investigate possible causes (unlike previous GPs). I have had several blood tests, a couple of which I understand (iron/thyroid). But she also ordered hormone and white/red blood count tests. What will she be looking for there do you think? Will get results later this week, just want to be prepared for what she might say. Thanks.
