Possibly implantation bleeding?

Alexis • 19 y/o. Mommy to Jahmari 👶🏽 11.1.17 MC 4.7.18 👼🏽

Last month my period was 2/13-2/17 the last time I had sex before my period was the 11th. On 2/24-2/25 I was spotting dark brown blood only enough to see on toilet paper. I have been having other early pregnancy symptoms I think unless it’s just my period about to start. Do you guys think this may be implantation bleeding?
