What does this mean!?!

Tr

So according to my last period I’m 4 weeks and 3 days. I know I ovulated around the 22nd. From opks I found out the day after my period was suppose to start and it was such a dark line. And today I took one again because it doesn’t feel real still we suffer from unexplained infertility. So I am just paranoid. The line popped up this dark in like 10 seconds and almost took the dye from the control! Is that a good sign? What does that mean??
