First period after having a miscarriage??

Shona-maree

I lost my first baby on the 31st of July. It's only been a little over three weeks and I think I have my period already. I'm not complaining, I just thought it would take longer and I'm not completely convinced it is my period. Two nights ago I had very faint, very slight pink blood when I wiped and then the day after there was a little more but never enough to actually go on a pad. Today I've had slight bleeding when I wipe and there's always a pink tinge to the water but barely any on my pads and it's a thick consistency and an almost brown colour, all three days I've had stomach cramps and sore breasts.. I'm just wondering if anyone else has experienced this? And if I can really class this has my first cycle? I just thought my first period was going to be heavy.. please help!
