So sorry @Fresas. It's such a precarious thing, pregnancy. A third loss must be incredibly hard to bear, I hope you get some additional medical support for next time, did you ask your doctor to refer you?
My tests have come back with everything fine except that I have a UTI, so waiting for my GP to get confirmation of what prescription to give me so that I can collect it. I asked the midwife about my blue lips yesterday, she said contact GP if it happens again but possibly I was just cold for a variety of reasons (dinner, exercise, tired etc). Still, my iron levels and thyroid are fine, so that's all good.
