blood clots (PICTURE INCLUDED)

Hello,I am a 18 year old female and i have had chlamydia and a UTI. I was treated and cured this year. A few months after that, I started seeing thick and big blood clots during my period,kinda like jelly. The only symptom i have is pain during urination sometimes,but that goes away a few minutes later. I wanted to know if thats normal during my cycle. 😩😩😩
