CD question?


I’m sure this is a stupid question, but i’m just wondering. I never get spotting before af it just starts full force. So It started around 1:30 in the afternoon Wednesday. I usually get it first in the morning and consider that CD1. Do I count my days changing in the middle of the day or just CD1= Wednesday, CD 2 Thursday, and today CD3. Or does it not matter. I was going to take my day 3 femera tonight either way it would be day 3 but i usually take it the evening of day 3, so should I wait till tomorrow morning. I’m thinking it probably doesn’t matter but just wondering what others think.


My RE says full flow before 5:00pm is CD1. So if I were you, I’d call Wednesday day 1. Good luck!
