Possibility of implantation ??? Help

Hey girls,

So me and my husband been trying for a month now to conceive. Last month we pretty much were active. The last time we did it, was literally on the day my period came. Like we did it and once I went to clean my self I had blood. So anyways, my period usually last 7-8 days. This time it was weird, so you know when your period is over it turns like brown. That happen to me and the following day which was the 9th I went to pee and it was light red but not like normal period it wasn't heavy or anything. Last till practically today which just turn tint of red. Is it possible that implantation isn't occurring?

Help

Regardless I'm calling my doctor tomorrow
