    So I’m having a pastel pink like blood with little clear stretchy like discharge. 5 days before my period is due to start… I’m supposed to start on the 12th. Could this be implantation bleeding?

  • Lauren Cramp


    My period is due on Wednesday(12/09) it is always regular, same time every month. But yesterday and today i have had light spotting. Yesterday was darkish browny colour in my underwear and today when I wiped was a light pink. I put a pad on as i thought I may be getting my period early and the darkish brown colour is now on that but only a little and that is all I’ve had in a few hours. I have slight cramping now and did yesterday. I did miss 2 pills in a row 2 weeks ago which I haven’t done since having my son over 12 months ago. Plus skipped another pill 2 days ago. Have just started taking the sugar pills today. Does this sound like implantation bleeding or is my body just reacting to skipping the 3 pills this cycle? I already have 2 children and have never had it before.
