CD21 blood work?

[Hope2be2013]

I got a positive OPK yesterday, so I am assuming I'm not Oing until today maybe? Today is CD18. I am suppose to be going on Friday for blood work and I will be CD23... Is that too early? Should I schedule it for next week instead?

I would. It's better to be late than too early x

How long is your cycle? You are supposed to do the 'CD 21' blood test 7 days after you ovulate..... You only get blood work done on day 21 if you have a 28 day cycle xxx
