Early sign of implantation

[Charlotteharknettx]

Hi ladies so I had protected sex on the last day of my period as I was very light , a day after I had light pink orange discharge and today the same! Is this a sign of implantation or is it to early to tell. My sister thinks that it’s old period blood coming out. I’m also getting bad cramps. Thank you.

Implantation generally happens 6-12 days after ovulation, so if you were bleeding the day after having sex, that’s way too soon for it to be implantation bleeding. Your sister’s suggestion sounds far more likely.
