Ok mamas I need some tmi advice. I've been on the Xulane bc patch for a few months I finished my period a little over a week and I never have spotting in between periods. Now since the last day of my period was on Tuesday last week I have been having extremely light red/pink spotting with no cramps and no other symptoms other than feeling exhausted and having a headache as well as aching pain in my way lower back on the left side. My question is could this be implantation bleeding?
