Uterine fibroids

Every time I come on my cycle towards the end I always have a sharp penetrating pain then a clot of mucus comes out of me. I just thought it was a "period clot" (Don't Judge) but I considered it normal.. Then someone told me it was uterine fibroids. I looked it up and it told me that I could cause infertility 😖😱 Does anyone else experience this too? I'm so scared because I'd like to conceive in the future
