Hi, I had started what I thought was my period 5 days ago. I had never had a period like this. I was about 4 days late, it was a bright pinkish orange color and very light flow my first day. My second day it was dark brownish-red and I passed a few small clotted, about dime sized. Then my third day I had absolutely nothing all day, nothing in my tampon or pad. Than the fourth day I started spotting dark brown almost black looking blood . Weird texture and it s lasted until now, my 6th day. What does this mean?
