Having cramping 10 dpo

So I think I’m 10 dpo based on ovulation symptoms etc but 3 of my apps say I’m 9 dpo. I was having sore boobs the past 3-4 days which I never have before my period. Today that’s gone and I just started cramping bad with cramps in my back. Not due for AF until the end of the week.. is this implantation cramping possibly or getting period early? I’m so nervous. Anyone have symptoms stop and still get BFP? Took test this am and was negative!
