I am now on cycle day 22 and 11 days post IUI. When can I take a HPT? I am suppose to call my RE on Jan. 7th if AF has not come and they will do a blood test. I am having a hard time waiting (of course), but don’t want to test too early and get a BFN and upset myself even more. I was thinking of testing on Thursday, which would be 14 dpo. ??
