Late period maybe tmi?

So, my wife and I are ttc using a known donor, Instead Cups, Preseed, B complex, Vitex, and prenatals. My last period was June 30th through the 4th. I have short cycles, averaging 24 days. We think I ovulated on June 8th (opks), so we inseminated almost every day that week, and the following week. On the 17th, I got another positive opk, so we inseminated again the 17th, 18th, and 19th. My period was due July 23rd or 24th, depending on the app. I'm technically 2 days late. Negative pregnancy tests. We were very concerned about a luteal phase defect, hence the Vitex. I've had cramping similar to AF but not as strong, and they come up more on the sides of my stomach. My right hip and back are killing me. I know cervical position isn't a good indicator of pregnancy, but usually mine goes low and firm and open about 24 hours before AF. It's still high, soft, and closed. No abundance of cm, but what I do have is very lotiony. Could it be that I didn't ovulate on the 8th, but did on the 17th, making me only 9dpo, but still late for my period (which I never am)? I know we can all only speculate, but I need some encouragement! Anyone else in this same boat? Any advice? Thanks for reading this far.
