Help! 12 dpo spotting and cramping

JustGoingWithTheFlow

So I'm not even sure if I'm posting this in the right place but I'm 12 dpo and took a hpt (FRER) today. Not fmu. Both test were faint positives. The thing I am concerned with is I have been occasionally spotting on and off since 8dpo and today I started having period like cramps. I'm totally scared and freaked out. Someone said it may be implantation bleeding/cramping? Advice needed! Anyone experience anything like this?
