Large blood clot and 10+ day period

Monica

My period was late by 38 days, when I finally came on, it’s been heavy and seems never ending. I’m on day 10 of bleeding and yesterday I passed this very large blood clot. I’m 53 years old so I’m assuming maybe I’m going through a hormonal change. But I’ve never passes such a large blood clot or has a period to ever last this long. Has anyone ever had a similar situation ?
