PLEASE HELP ASAP

I took my nuvaring out so I could have my period this is my first time doing it since I’ve had it for a few months. Today’s the 3rd day I’ve had it out and my cramps have been terrible and I felt a “blood clot “ come out and it was a super sharp pain and then I see this and I don’t know what to do and I’m freaking out and yes I’m sexually active
