Ov testing help!

Ok ladies I need help! In July I had my nexplanon removed, had af for 2 days and then nothing until the end of August. The 29th-1 My AF was heavy. since I didn’t have a period the whole time I was on birth control im not sure how long my cycle is, but these are my recent ovulation test and I should have started hear right after my period to see how this works, it seems that the first day I did these they were darker than today so as they get lighter does that mean I have already ovulated? 🤷🏻‍♀️ we are really hoping to conceive soon. We dtd on the 2 nd ,5th 8th and the 9th because I have noooo idea when I will ovulate.
