@mo22 if I'm recalling your story correctly, you've had some blood for a day or two now (apologies if I have this wrong!). So you may find you do see more blood over the next few days. If you get to the stage you're soaking through a sanitary towel in an hour, you should contact EPU again (or NHS 24 if it's out of hours).
If you do end up waiting and having a miscarriage naturally, a few wise women on this thread suggested a few handy things to help: some thick sanitary pads (more absorbance the better), some puppy training pads (I had to sit on them in the hospital, really helped with leakage!), and something for the cramps (hot water bottle, comfortable old clothes, paracetamol).
It's shit, really shit that we're all here united by a horrible experience, but it's a good group with lots of support.
