My mc started with a tiny bit of pink when I wiped, then built up over the week as red or brown, with no cramping. A scan confirmed the embryo had died about 3 weeks previously, and the day after the scan the mc actually happened, with period cramps (nothing that 2 ibuprofen couldn't handle) and heavy bleeding.
However I have had a lot more bleeding with this pregnancy (now 35 wks) - bled throughout the entire 1st trimester, so bleeding isn't necessarily anything to worry about, and there are loads of non-dangerous reasons for it.
I wouldn't focus too much on the symptoms, they can come and go at this stage. Being off your food is probably due to anxiety, and energy levels, nausea etc seem to vary according to how tired you are, what you have eaten, iron levels, hydration, anxiety, and which particular part of the embryo has developed that day.
If I were you, I would try not to worry too much - they have found a heartbeat, which gives you a better chance of everything being ok. Keep an eye on the bleeding, and if you get more over the next few days, or if it's bright red, give your midwife or epu a call.
