So, I m having my period, it started yesterday, and then when I pulled my tampon out, I realized there is something white? I think it s a discharge but I don t really know. So, um, I, checked and, the white thing is string-like (its like cell?) and it seems to kinda have mixed with blood clots so it kinda freaks me out, what is it? I can tell more in detail if needed. It s also not sticky or anything.
