Hello, my 13 year old daughter has extremely thick clotted blood with period. She has used a tampon twice and both times has fainted - her skin turned extremely greenish and her lips became the color of her face (extremely pale); she had chills and clammy skin. I removed tampon which was very black and caused pain upon removal (it had been in for only 10 minutes). I put her in the bath and was surprised by the amount of clots and almost what looked like small tree branches (dark red in color) that came out from her. I apologize for being so graphic, but I am wondering if this combination of symptoms is cause for alarm. Perhaps she just panicked from the tampon and her blood pressure dropped. Perhaps this type of menstrual flow is normal - I ve never really had the opportunity to observe so closely before! Any thoughts?
