Cramping and BFN

Kristina • Blessed Momma to Aiden Joseph 💙❤️💙❤️

So I have had all kinds of pregnancy symptoms the last two weeks. I have also been cramping on and off through it all... yesterday I had some pretty intense cramping and then it just stopped. AF due today and no cramps now. My boobs are crazy sore. I tested this am and got a BFN :( is it possible I implanted yesterday and my levels are still too low?
