Hey lovelies, so I've been TTC #1 for 4 cycles and have been tracking bbt since. The first 3 months were orally and I switched to vaginal as I read it was more consistent. Below are my charts. Would you say, in comparison to charts 1,2&3, that 4 is a triphasic pattern? Feeling confident this month ☺️ what are your thoughts? Thanks in advance.
