Is implantation something like your last period before pregnancy? I'm now starting to notice its starting to turn kinda dark/brown. My head hurts.

R u pregnant? . Implantation bleeding seems to be something that's more common on the internet than in real life. It is not something we obgyns pay a lot of attention to. Have you done a home pregnancy test to confirm that you're pregnant? What you're describing sounds more like a period.
