What do I count as my 1st day?

brittlato • 2 miscarriages and two successful pregnancies! Check out my YouTube channel forum pregnancy birth stories!!
{since my miscarriage}  I have: 
 
3-4 days spotting
1 day w/med bleeding for about 6 hrs  3 days of dry or very light spotting, 
2-3 days of heavy bleeding
3-4 days more spotting
So what do I count as my first day?   It's hard to chart with this. I've been told it's just my hormones still out of whack (still get random morning sickness too)  thanks!
