I Had Experienced What I Think Was An Implantation Bleed

I had experienced what I think was an implantation bleed for 3 days light red/pink blood with other symptoms like food aversions back ache sore boobs however today I had one flow of red reasonably a good amount with I thought oh okay My period but then after I had light pink blood again it hasn't been 2 weeks since the 3 day bleed so I haven't took a home pregnancy test
