Hi,

I suspect that I have low progesterone as I have a short luteal phase, although I don't suspect any problem with my actual ovulation. My GP has told me to get my mid-luteal phase progesterone levels checked, but my luteal phase is only 9 days. Do I go on 4DPO (mid-luteal) for me, or 7DPO (but my menses will be starting 3 days later)?

I'm worried in case 4DPO levels are too high and the doctor won't help, but if they are too low on 7DPO, they will suspect ovulation problems.

Thanks in advance.
