Really confused...

So I had my period on the 14 of December, and this is my ovulation week and today will be my last day. But since this whole entire week that I have been ovulating. Me and my man been having unprotected sex. He has been cuming in me that whole entire week. So yesterday I woke up with dark brown/ red bleeding and the bleeding has been light enough to where I been using pantie liners for almost 2 days now. I have been cramping having lil blood clots, and feeling nauseous and irritable. Idk if it's another period within the same month, or implantion bleeding, or ovulation bleeding idk what it is 🤷 I will actually be making an appointment tomorrow don't know where to post this so forgive me if this is in the wrong group but what are your guy's thoughts on this 🤔
