OPK confusion!

Kindra
Hi! I'm a bit confused with my opks this month! A short backstory..... I'm 31, I have 2 AMAZING boys (adopted) and we are trying for a third child to complete our little family! I was told I don't have PCOS but I don't ovulate. After 3 rounds of clomid and a chemical pregnancy my dr referred me to a specialist. Husband and I wanted to take some time off from trying after the chemical and I started opks again last month. Out of 20 tests last month I never got anything darker than a "so light you can barely see it" line and then this month.... It's all over the place. I thought that the second one from the top was me getting a surge but now I don't know. AF is due the 26th, so isn't it way too late to be getting a surge?? ****this is an UNMEDICATED cycle.... I've never had lines this dark even on clomid.....
