You ladies are so knowledgeable I just know I’ll get some educated answers here!

So I’ve been doing OPK’s since CD8.

On CD 10 (which is 5 days after my last clomid) I tested at 11am & 4pm. Both had a reasonably dark second line but not positive. In the evening around 7pm I had cramps and discomfort so I thought it wouldn’t hurt to do another OPK, the second line was so dark it was NEARLY positive but not positive.

By 11am the next morning the second line was lighter and now two days on the line is nearly non existent.

Would you say I’ve already O’d and Just missed the peak whilst testing or is it normal for your levels to rise and fall and I’ve not yet hit my surge?
