Question?

Chelsea
So I am two weeks and two days late for AF. I have taken multiple tests and all have been BFN, the most recent one on Friday. Well today I have had a tiny bit of spotting. Just enough to show on the toilet paper and then it goes away. Anyone have this happen ask got a BFP this late in the game? I don't think it's implantation because I haven't BD in about two weeks. Any advice would be appreciated! Thank you and baby dust to all!
