How many days past Ovidrel 250mcg (6500iu equivalent) did you test negative?

Cj • TTC # 1. Mild male factor + unexplained. IUI failed x2. Saving for IVF

My line quickly went faint but seems to be the same the past 3 days. Even a little darker yesterday

But I’m only 7 DPO so I know it’s not a positive. 😕

Just wondering how long it took for others.
