Implantation bleeding !!

Ladies, please help who have had implantation bleeding. I have already been a little concerned about my pregnancy test, not having a darker line after time. It was brought to my attention that I could’ve ovulated later than I expected but then last night when I wiped there was a pink color, today I have more of what could be spotting or an early miscarriage. I am not 100% sure. I’m having mild cramping and bleeding.  can anyone give me their experience with implantation bleeding.
