If you start at 2pm, does CD2 start at midnight or at 2pm, so 24hrs, the following day?

I have done IVF and always been told if you start after 12noon CD1 starts the following day :)

Cd1 is the following day? What do you call the day you come on then?! Confused

You count it as part of the previous cycle if you don’t come on until after 12noon.

Hmm not sure about that as that's discounting a half of a 24hour "period". I get that if you come on at 10pm to assume cd1 is the following day.

I’m telling you what I have been told by my IVF Drs and Nurses, and what is very common and standard practice in the world of fertility treatment. If you aren’t doing fertility treatment then I can’t say that being so exact really matters so do what you want :)

It's a warm up!

I always counted cd1 as the first full day.

No I'm not even ttc but I like being in tune with my cycle!
