* I have not been keeping up with my cycling like I should*

*I do know I start my period around the end of the month*

I started bleeding on the 23 a few days ago it was very light pinky brown then a few minutes later I couldn’t hardly walk the pain was so bad and I was bleeding heavily and had clots. I felt the need to push the whole time this pain was happening. After that day I was just had mild cramps and just spotting. Now it has almost completely stopped. I am just confused I have never experienced this before.
