What is the latest to O on Ovidrel?

I know typically they say it is around the 36 hour timeframe. I triggered on Friday evening, I took an OPK on Saturday and it was negative. I wasn't able to take one yesterday.I've had hardly any side effects except for some extreme fatigue. However, this morning I've been feeling alot going on down there..alot of pinches and twinges.

Is it possible that I am Oing now, over 48 hours after I triggered?

Doesn't your RE do u/s to monitor O? Mine does.

I have never O'd more than 36 hrs after trigger. Never.

.... not to say that it's not possible. I'm uncertain.

I think 48 hours

RE does monitoring, however, closed on Sundays. Perfect, right?? I won't know until late this afternoon. This is why I am switching REs.

I believe it is 72 hours.  I have gone for 4 IUIs at 36 hours and I haven't O at that point at any of them.  I am fairly certain that at least for 2 of them, I felt O cramps closer to 50-60 hours later and my RE has always told us to BD the day after the 36 hour IUI.

36 hours post trigger is average but of course there is a window on either side. With my last two IUIs I O'd around 33 past trigger.
