Blood clot

Okay I just wanna know if I’m worried for no reason. My period came on time surprisingly. First day I was spotting very lightly (light pink) then it turned brown and later that night I started cramping.

The next day I was bleeding sorta heavy and I was having severe cramps. Usually I’d spot for a day or two and my period would start off light but not this time. The Pain was so bad, it was in my back too. I was feeling nauseous later on and at night right before I went to shower, I passed a big blood clot. It was bigger than a quarter and bigger than I’ve had before. After the blood clot passed, i had some cramping for a little bit after that then it stopped.

On my normal periods I’d have cramps for two-three days and little clots here and there but this time after the blood clot passed, I was fine, i did have gas the next morning and it hurt trying to have a bowel but other than that I’m fine and no more cramping.

Am I worried for nothing?
