My period was late this month so I took a test and it came up positive. This was done on Sunday. Today I've been cramping up alot, some mild, some a little more than that. I came home from work to find that I started bleeding. I took a second test and this time the results didn't show up immediately, it took around 5 min and the lines weren't solid, instead they were somewhat faded. I'm still feeling some cramping and I'm still bleeding. Could I be miscarrying?
