What day is cycle day 1?

Question

I’m getting confused on when to list cycle day one today I’m bleeding heavy and red. But yesterday it was just dark brown and light. Do I start cycle day one today or yesterday?

Answer

My doctor said day 1 is the first day of full flow - not spotting.

Answer

So I was at my obgyn yesterday and asked this very question and she said day 1 is counted even if there is just spotting. I'm getting my hormones tested so this is why she was so specific. I don't think glow counts spotting as a day tho.

Answer

I consider the first day I see blood, whether sporting or heavy, to be day 1.

Answer

I say yesterday only because that’s when it actually started.
