16 and miscarriage

lauren

i kinda thought i was pregnant because i had been super nauseous and had missed a ovulation cycle but i never took a test to find out. last night i thought i just got my period but when i looked down in the toilet there was a lot of blood and clump (kinda like a blood clot). i was cramping bad all day and bled heavy for a while. today, no period.

did i miscarry?
