sorry but i think it is a bit insensitive of your docs to say it sounds like u are having a mc, cramping is normal in pregnancy and spotting is very very common, women go on to have healthy babies so i think they are being a bit rash saying that to you.
just try and relax and put your feet up hun, i have had a mc in the past and when i spotted it was bright red and was loads of blood, plus pg tests faded by the day. You sound ok so far x
