Could it be implantation bleeding?

Angela
Ok so AF is due in two days and when I went to the bathroom I had blood on the toilet paper. It was light pink and not very much. But then went I went again later there was nothing. Could it be implantation bleeding or just because AF is due soon? My husband and I have been trying to conceive for a year now andI don't want to give my hopes up if it's just nothing. Thanks for all the imput!
