I am trying to conceive. I have been experiencing spotting ( nothing on pad, its there only when i wipe with tissue, or more like reddish brown mucus discharge) on and off from past 3 days. My period is due on 11th April. Could this be implantation bleeding? I have mostly all the other symptoms i used to get during my normal periods other than the heavy period flow. So i am confused. When should i do a home pregnancy test? Please advise.
