help with positive OPKs

so.... my ovulation wasn’t supposed to happen until the 13th of march.. (i have irregular cycles- 30-40 days) i usually don’t ovulate and when i do the line is barley there.. I just happened to test after having unprotected sex and it was darker than the test so i uploaded it to the app and it changed my ovulation date to the 9th... i had unprotected sex again on the 10th and later took another test with the line way darker than the control line! Uploaded to glow and it again changed my ovulation date to the 10th saying on the 11th my ovulation cycle ends??? I’m really confused.... Can someone please let me know about the changing dates and two positive OPKS? and more importantly.. what are my chances of pregnancy? Thank you so much for any answers.
