I'm 8w 2d and whilst in the shower half an hour ago I started with brown discharge. There is quite a bit when I wipe but it is definitely brown at the moment. I'm sat here scared and don't know what to do, I'm terrified that this is the beginning of a miscarriage. I am due at the EPU tomorrow for a follow up scan after some bleeding at the beginning... they put it down to implantation but wanted to check me again in two weeks. Do I ring them tonight and see what they advise?
