Massive blood clots after birth control?

How normal is it for us endo folks to experience big, and I mean BIG, blood clots after using birth control?

This paragraph is just context if you want to skip, but I was taking birth control (Ocella) and norethindrone acetate every night for the past 5 months or so in order to deal with my endo symptoms (didn't have a period in all that time). Fast forward to present day, I've been prescribed the SSRI Lexapro for anxiety, and I (being the idiot I am) decided I didn't want to take norethin ace anymore because that felt like too much medication for me, and a lot of women can take just birth control without getting a period.

And you guessed it, I got my period, and she's back with a vengeance. I just passed the largest blood clot I've ever seen in my life. I hesitate to even call it a blood clot because it genuinely looks like a tongue. It was at least 5in × 2in and thick with membranes. I don't want to say a piece of my uterus just fell out, but that's what it fu****g feels like.

Am I in danger lol?
