OPK frustration... Help needed!

Victoria • My partner and I have been TTC for many years with no luck. We`ve had 4 Miscarriages and 1 Ectopic pregnancy. It`s been a stuggle to get pregnant and stay pregnant.

So for the past 3 days I've taken 3 OPKs. The first day (July 27th) I got a negative lighter second line. Then the second day was also negative and looked the same as the first opk. But the the third day I got the exact same result, negative. It was slightly darker but still lighter than the first line.

Glow says today is ovulation but I never got a positive opk. I'm thinking maybe I had a LH surge last night during sleep which would be depressing because hubby and I can't DtD until later tonight after work.

I'm wondering if anyone else has experienced this? Will I miss the initial egg release this cycle?

I'm so frustrated... :/

Below are pics of the OPKs. (Dollar Tree brand)

The white & purple background was today (July 29th).

Black background was yesterday (July 28th).

Brown background was 2 days ago (July 27th).

I did take OPKs before these ones but the lines were extremely faint so I tossed them.
