Help understand ovulation tests please ladies

So this is my first month using ovulation tests, I’ve had sex for the last two days and this morning, this morning I took a test and it wasn’t quite positive but getting there and tonight I had a positive ovulation test but won’t be having sex again as I’m currently waiting for a flight to Dublin without my man 😂🙈😢, do I still stand a good chance because I thought when you had a positive test it meant you was ovulating now, but according to what I’ve read online it means I’ll ovulate in the next 24-48 hours 😫 does that mean that sex this morning might not have been enough? Sorry if I sound thick but this is new to me
