I was due on my period on 13 Dec. had abdominal pains since last Monday but stopped today . Had a little spotting when I wipe myself witch started as a brown discharge but as gone to watery pink colour is this implantation bleeding or my period coming confused never happened before

With one of my pregnancies I did experience this also - I didn't need a SP but it was there for a few days. But in saying that I also sometimes get it before my period.

I would wait until your actually late for you period then take a HPT.

Best of Luck
