Need help.

Ok so I have irregular periods and I just started taking BC in March to try to help with that. Today is 3 months since my last period and how that is normal for me because of the irregular periods. Anyways for the past week I’ve been having cramps so I just thought my period was coming since I really only get it around every 3 months. So Sunday when I was out I thought I had started my period so I went to the bathroom and when I wiped there was just a light pink color to it and went on with my day so then later that night when my boyfriend and I got home I went straight to the bathroom and it changed from the pinkish to almost a maroon color so I had just assumed it was my period and got fixed up and what not. The next morning, which was yesterday, I woke up and seen that there wasn’t any blood so that was confusing to me as that’s never happened so I just went on with my day and then these cramps were just getting worse and worse to the point where I couldn’t sit but it hurts to stand, I’m in tears, I can’t breathe, and my younger sister was getting scared and was gonna call my grandma for help. My sisters 12 so she’s not really familiar with this stuff but I told her not to call and that it’s just cramps it’ll go away.. so I went to the bathroom and well it was just my period a huge blood clot I felt like I had just gave birth to a jellyfish😂 anyways this morning I woke up and didn’t feel right it was so hard to get out of bed with all of the cramps and when I got to the bathroom as soon as I pulled my pants down out came this.. I’ve never seen anything like this, and it’s never happened before.

is this normal? Just my period or should I be more worried? Let me know what you ladies think.
