so yesterday I had a pain in my side as if I may come on my period early which sometimes happens anyway I had this pain and all of a sudden it went well I went to the toilet later on to find a pinky browny discharge only a bit I though oh that's strange but it never continued I've had nothing since I thought it could of been one of those odd starting periods but it never progressed still nothing so far today slight pain again and I'm very tired ... any ideas what it could be my first thought is implantation but I don't know ? Has any one had this and not been pregnant ? I don't want to get my hopes up x
