Sex before ovulation and pregnant

Wondering if it's likely I'll get pregnant if I had sex before ovulation.....

Story - glow originally said 15-21 was my ovulation. I baby danced 17, 18,21. My hubby left for work today and I went to my parents house and got the easy at home ovulation tests in the mail I ordered and was gonna save for next month. I caved and took one. It was positive so i put that into glow and it changed my ovulation 19-25. Wondering if its likely or not ill conceive. My period is due on September 3rd and its my birthday. And would be the best gift ever to have a big fat f-ing positive. I am turning 20. Came off birth control in June. Husband is 38 and desperately wants a child. Not sure if ages matter but just all details. Not sure if his age effects it at all. Thank you for info.
