Day before LH surge sex?

So I did opks this month and next month we are ttc, but this month my husband just didn't feel like pulling out for once. My cycle is 33 days long. We dtd on the night of the 24th leading into early morning the 25th. So around midnight. I was having clear fluid but tested positive for lh surge on the 26th. The 27th was getting lighter. So are the chances high to conceive or no? I mean I'll be asking this question in a few weeks anyways. Lol.
