Implantation?

The day before AF was suppose to show her face I had a very light pink color when I wiped using the bathroom, so I thought I was going to start and went ahead and put a pad on. All that came out was about a penny size drop. Which I thought was very weird ( usually when I start it's like a river) and I haven't bled since. The day af was suppose to come in got a nose bleed which is VERY odd for me, I haven't had one of those since I was about 10. And now I am a day late but still getting a BFN...im not having any other symptoms other than being very tired and my boobs are a little sore (not even as much as usual) what do yall think?
