Tmi period talk

I was in my bath tub & idk like I felt something about to come out of my vag I thought it was blood it wasn't it was like a huge stringy something. Not just one strand of string it's so hard to describe. It looked like that seaweed that's all stringy. Best way to describe it tmi. I never had that before also my mom had fibroids on her uterus & ovaries she would bleed like crazy so she had a hysterectomy. Is that what I'm going to have ??
