Help me

I have been on the pill for about a month for the first time. I take it at the same time everyday but a month before I got on the pill I went on vacation with my boyfriend and we did it a lot 😅 I was 3 days late on my period and then I woke up last night to very very bad cramping and a giant thing that resembled a clot but looked like more skin came out on to my pad... what is it?? I have a picture of it and if you all want to see I will post but it’s kinda nasty.. I’m just scared please help.
