Classic, the cycle before this one I had loads of positive tests and then they started to get fainter and I started to spot the day before then bleed on the day af was due, but it was weird with a super short proper bleed then the rest of the time it was barely there. I then had more positive tests getting darker, then fainter again and eventually they gave me a beta which came back as below 1 so my guess is this was possibly a very early loss and this is why your period was weird because that first test you posted was very there and very pink. I'm sorry, it makes it harder when things don't go how you expect them to as they usually would, as if it isn't hard enough already
