Opk question please help ladies !

So we BDed on Monday May 19 and then noticed yesterday May 23 rd that I almost had a positive opk. We BDed this morning May 24 th twice and I did another o test and got a test line darker than the control. We will bd again tomorrow and for the next few days (hopefully). Is this good enough to get the egg during the right time? I'm reading before is better than after the surge etc and some saying to do it on the day and after ... I just hope I'm getting it on time!! Please help !
