So, last week (before I even ovulated) my doctor gave me a prescription for this and told me to go on Friday 1/15. I actually didn't O until Monday, so Friday would only be 4dpo. The lab is closed Sunday and Monday, so my options are to get the bloodwork on either 5 or 8dpo. Which one is better for the progesterone test to be most accurate??

I tried calling my doctor just before, but was placed on hold for a very long time, and I had to hang up. I'll call back later on during the afternoon, but I was just wondering if anyone found themselves in a similar situation...
