Anyone on gonal f had problems with opk?

The two times I took gonal f, it looked like opk wasn't picking up any lh surge, even when I thought I was very close. First time was with cancelled IUI a few months ago.

Yesterday morning they said I had two mature  or almost mature follicles on both sides and told me to take opk and if it's negative, to trigger with ovidrel and come in on Friday morning, but if it's positive, come in the next morning (this morning).  Opk was negative so I triggered.  My problem though is that I was really feeling full ovaries yesterday and I felt like my lines should at least be getting darkers, but there was nothing there.  Usually, I get gradually darkening lines and then a very strong couple of days at ovulation.  But this was nothing, there was almost no second line at all.  It seemed weird to me.  I even got a digital one and it was also negative.

I'm really afraid of missing the ovulation, of ovulating on my own but not knowing it because the opk didn't work.  IUI is scheduled for tomorrow morning.

Anyone have problems like that?  Would gonal f mess with opk?

Lines do not get darker or lighter with OPKs - either it is possitive or negative. What causes the line to darken is an LH spike - that does not happen gradually, it just happens at once. If you are triggering that will cause an LH surge and your eggs to release.

Actually, on my non-medicated regular cycles I do have lines darkening for a couple of days prior to the lh surge and then really dark lines for a couple of days.  I've been doing that for the last couple of years and it's always the same. Maybe it's different for different people.  But I never go from no line at all to a completely dark line from one day to the next.

What I meant to say, is although it does happen, it means nothing. You can have a LH surge without progressively darkening lines.

I guess what I'm trying to ask is can gonal f make opk not work for me when usually on a non-medicated cycle opk always worked for me.  I just don't want to miss it   Hopefully, it's fine and I'm going to ovulate after the trigger that I did last night and tomorrow morning will be the right time for the IUI.
