IMPLANTATION BLEEDING???? - and its not one of those maybe implantation?

my implantation bleeding was pink...every other time i had "spotted" or was about to start my period, the blood was brown or dark red. so when i saw a bit of pink on the toilet paper and then nothing, i realized i may be pregnant. I took the pregnancy test about 14 days after and sure enough it was positive (about a week after i had the implantation bleeding). my cycles are anywhere from 28 days to 35 days and i took the HPT on the 36th day with a positive read.
