Opinions?!?

So… Normally I use the app FLO… And according to that app my period was due on March 3. I had a bunch of odd symptoms a lot of cramping all of last week a little bit of nausea sore breasts… And then I started spotting yesterday morning. Very very late PINK. With me. Normally I never spot and when I cramp my period comes almost instantly afterwards and usually it’s dark red to brown. Normally my periods only last 3 to 4 days and is not heavy whatsoever.So this light pink spotting threw me off. As the day went on it got a little bit heavier and darker but today The bleeding let up a lot I don’t even need to wear a pad or tampon or anything. is there ANY chance this is implantation? Has anyone ever had implantation that resembled their period ?? I know implantation isn’t only a light pink blood and there are cases where women actually think it’s there period . Just looking for opinions
