Light spotting :(

Meagan
Hello all! I am currently 4w2d. When I woke up this morning I noticed some light pink spotting when I went to the restroom (and it was a very small amount). I have read where it can be normal, but I have not had intercourse or anything that I have read that could cause it. This is our rainbow baby and I'm praying things aren't heading south again... I have had some mild cramping/pressure ever since I found out I was pregnant. Has anyone else experienced this?
