Confused...

My BF and I had sex at all the right times, and I was starting to get excited because I was two days late on my period( I just had some light brown and pink discharge that was stretchy and thick), and I woke up this morning knowing I AF was creeping up, sure enough AF is here. Part of me still hopes maybe it’s implantation bleeding and will stop but I don’t think it will. Has anybody else experienced this? I really thought this was it.
