Implantation bleeding and when to take a test

Laura

Ok so yesterday when I got up I thought my period had come early but turns out it was only a tiny bit of light pink blood when I wiped. I put a liner on and when I checked it later only a tiny bit of brownish blood. Similar brownish blood this morning. Could this be implantation bleeding? I had some cramps last night too.

Should I take a test? Or is it still too early? My period isn’t due for about 4 days but I’m desperate to know.
