Miscarriage?

I have a question for some of you ladies. Sorry for the long post by the way..

Little bit of a back story.. I had a missed miscarriage at 12 weeks a few months ago so I obviously didn't have bleeding or the common symptoms of a miscarriage.. and I had a D&E; that same day.

I'm now 8w4d with my rainbow baby. I've had 2 ultrasounds and lots of blood work and all looks well.. but for me it all looked well last time and wasn't. But for the past few days I've been having cramps. I had brown spotting at 6 weeks.. it stopped. Doctor put me on pelvic rest.. and since hitting 8 weeks the brown spotting has returned again.. Every other day really. I'm just worried since I'm also having cramps. But since spotting and cramps are "normal" in early pregnancy but can also be a sign of miscarriage in just confused and scared I guess.

So my question is.. for you ladies who have experienced loss (I'm so very sorry, I know how heart breaking it is) how did your miscarriage start? Was it serious cramping/heavy bleeding? Or did it start with light cramps and brown spotting?
