Have I ovulated?

Hi All,

Please help:

According to my doctor, my fertile window was between August 23 - 29th, and August 25-30th as predicted by Glow. I started using OPKs on Sunday 27th but am a bit confused by results.

Please look at my opk results, and let me know if Ive already ovulated.

The topmost test was taken on Sunday, the bottom one was taken today - Wednesday 30th.

The other two tests

were taken on Monday (second from top) Tuesday (second from bottom)

All tests show that I did not ovulate in the 4 days, but The Sunday test (the first test) seems to be the darkest.
