I'm 4w 3d and last week from monday til friday I started spotting a brown color. It only lsst those fives days so I figured it was implantation bleeding. I had no serve cramps just the normal ones every once in awhile. Then yesterday and today I've noticed some more brown spotting. Its never enough to need a pad or anything just when I wipe I can see it. I'm nervous I may be having another miscarriage as I had one in february. Can someone please help! Thanks
