Spotting and 5 days late?!?

So I had a faint BFP a little over a week ago but negative digital I was waiting to test again until a week after missed AF bc I've never had luck testing before that. And SO was out of town so I wanted to wait until he got back. I was cramping a little yesterday and had vvvvlight spotting we did the BD and I had no signs of blood what so ever. and this morning I woke up and still spotting but a little more pink nothing bright red or alarming and I'm not cramping. I'm confused 🤷🏽‍♀️
