I've been really unwell for a week with terrible back pain which I just put down to lifting by DS - but it has now localised to my left side and abdomen, night sweats and got cracking headache. We have some urine stick sample thingies in house and I dipped urine - has come back high in protein. But - I also have period. Could raised protein just be due to period?? On my own with two small children so doctor appointments tricky - and really don't want to waste their time.
