TMI (BIG blood clot)/ bleeding for a month

so since the second week of November I have been experiencing some strange symptoms. i have an irregular period already so i never know when I’ll get it. but since the first week of november i have been bleeding everyday but it’s very light and is accompanied by a blood clot. in the picture it’s a big blood clot but they always vary in size.

so usually i’ll be okay all day until around noon and i’ll feel wet so i go to the restroom and there’s a light bleeding and once i use the restroom there’s a clot in the toilet. i usually put a panty liner or a pad because i’ll bleed afterwards for a little while and then nothing for the rest of the day.

i went to my primary care physician and i had a papsmear & pregnancy test done and i wasn’t pregnant and the papsmear came out normal.

my question is has anyone else experienced this before? what could it be? /

i’m thinking i should probably see a gynecologist since my physician didn’t say anything about the bleeding. also every time i try to have sex, i bleed too.
