Please help me! Blood clot? Is something wrong?

an

Okay so I’ve been on degesterol pill for a month now, I’ve had brown spotting for 14 days - starting two days before my period would have started had I not been on the pill, but today I woke up and had bleed a lot, what looks like the start of my typical period. Throughout the morning since I had only a pad on as my ‘period’ was light and I noticed a large red clot in the toilet when I peed (tmi I’m sorry but I need to say it as it is!). I dismissed it because I thought well I’m on the pill, it’s new blah blah. I ended up putting a tampon in, I then went to pee again and I felt i needed to take my tampon out and out came another clot and when I wiped there was this!

First of all, there’s no chance I’m pregnant, and I’m only 16 but please do not judge me, I am on the pill without my parents knowing. It’s almost solid.

Should I be worried? What should I do?

Sorry for the long post but I need help, thank you.
