CD21 test and short cycles

[Redfraggle]

I know I could probably google this and find out but thought I would try you girls first cos google is evil!

I have had a letter saying I need to book myself in for CD21 blood test. Now I only have a 24 day cycle. So do I go in on CD21 or before that???

If you know when you do ovulate then go in 7DPO.

If you don't know when you ov then go for it on day 17 (7 days before a/f is due)

good luckx

Thanks Chanel!

I chart and use OPKs so know exactly when I ovulate.

Looks like I am off for blood tests next week then!

I shouldn't think there will be any problem with your blood test results then

One good think about getting the progesterone tests is that it breaks up the 2ww a bit
