I had a positive digital pregnancy test about 1 1/2 ago. From then on I've had faint positives. On Sunday it was when I was to start my period. I started spotting very light bleeding its been, it's been 4 days of light bleeding (not enough to fill a pad and my normal is very heavy bleeding). Today it's been brown looking blood very little. I have had no cramps or discomfort. Is this normal or should I be worried please help. I told my husband I may have miscarried but I've had no pain and not a lot of blood.
