First IUI W/femara and trigger: pos OPK day of AF?

Charleen

A little background: we are on our first cycle of IUI. We had our IUI on 4/9 with a trigger shot of Ovidrel on 4/7. I have tested out the trigger shot with both ovulation and hpt. Today is the day AF should show up but she can be late a few days some months. Anywho, has anyone ever gotten a line on their opk before AF? hpt say negative on cheapies any advice 😁
