Spotting and scared!

Ashley
Started spotting Friday and it was pinkish brown and was only visible when i wiped. Went away that evening then started up again Saturday little bit more heavy mostly when I wiped but a few drops in my panties. Today Sunday still spotting still only when I wipe and few drops in my panties. This is my first baby and I'm scared to death. Going to call Dr in the AM on Monday but wondering if anybody else is having any problems?
