Implantation bleeding or period?

Crystal

So today would be my 3rd day being late for my period but at 4 a.m. I started getting slight cramps not period cramps and brown blood. Then, it stopped. Then when it started again it was light pink brownish. Now it’s still going. I’m never late for my period and I am trying to conceive but it’s so hard to not have the internet drive you crazy. Can anyone help ? Greatly appreciated ❤️
