Implantation bleeding? Please help…

So my last period was April 17-21 and i was supposed to start Saturday the 7th.

I’ve had cramps, nausea, sick the past maybe three mornings, and sore breasts and painful nipples to name a few things.

Last night i started spotting this pink color and today it was brown until tonight it was pink again. Very light, just a few spots on my liner and only there for one wipe.

I took a test Sunday and Monday and they were both negative, don’t know if it was too early or if I’m like my mom and can’t get a positive test unless i get a blood test
