Ovulation Surge(CLOMID)

Gigi

Hi girls, I shall expect my period in 2 days, but my LH surge came like this today. I had one medical screened and proved ovulation 16 days ago and since then my ovulation tests were coming back negative with no second line at all. Can I have a second ovulation this month? Can that be due to being on Clomid? I know this test is still negative but I have been testing for 3 days now and the surge keeps getting darker and darker. Here is a photo of the lat one today.
