Red spotting 5 weeks 5 days

Brittney
I had my positive test from the Dr. On Friday. I have been spotting since yesterday afternoon. I felt cramping, and got up and had a BIG bowel movement (TMI) and that's when I first saw spotting. My cramping stopped immediately after. This morning I had another cramping episode and yet again, after I went to the bathroom the cramping stopped. And the spotting started off not very much, it will slow down, then start back up again. I only have it when I wipe, it's not soaking my underwear or anything. This is my second pregnancy and didn't experience any of this with my first. I have my first Appt tomorrow afternoon. Has anyone else experienced this? The more I've read, this is more common than I thought and for everything to turn out ok, but sometimes it doesn't. Thank you!
