CD 20 blood work

Hi Ladies!  I was supposed to get CD20 bloodwork done for progesterone, but since CD 20 was a Sunday, and in my rural area nothing is open on Sunday (seriously, the lab in the hospital closes!!) they told me to go today.  So, I woke up, ready to go... And there is a huge snowstorm.  Call the lab - closed.  Call my obgyn - closed.  Now I'm all sorts of stressed tomorrow will be too late!  What do you guys think?  Will CD22 still give me accurate results? It would be 9dpo.  I have a 25 day cycle.  Really hating this snow right now!!
