Out of curiousity

Hey well I'm new to this app. I started my period January 1st to January 5th of 2019 well then I just started bleeding again January 28th 2019. In the same month weird right? Well I never have two periods a month. I'm just wondering can I be pregnant and be implantation bleeding right now and for the past 4ish days. It's dark red and not to heavy.
