Crazy silly little question. Last night before my trigger, my OPK was definitely negative, barely a shadow of a line there (I am really convinced this follie was triggered far too early, but, not my choice). Then I triggered, and now the OPK is moderately dark but not as dark as the control line. I thought hcg (ovidrel) would cause an OPK to turn positive? Why is the OPK still so faint? This IUI is going to happen a day early I think.
Trigger takes 36 hours before you ovulate.
