clots

My period was 4 days late. I started yesterday, I always have bad cramps and I did this time too but there was a lot of clots and not much blood. That's not really normal for me. My periods have been getting lighter though. I have been trying to eat healthier sticking to mostly keto but i cheat ever now and then lol . Do you think my clots could be from my diet change or possibly something else?
