12DPO- thoughts?

Alex

so I had what i thought was implantation spotting and light cramps since 10dpo. today I took a test and it was a bfn which is okay because it's still early if I did implant two days ago. originally spotting was superrrr light pink when I wiped but today its brown so I'm afraid AF is coming. to back up, I've had super sore boobs and cramps for almost a week now! has anyone had this happen to them?
