Help please!

Okay so my fiancé and I are trying for our 3rd baby. I’m 30 now and we had our 2nd daughter 2 years ago and I got pregnant super fast. Now we’ve been trying for like 3 months now with no luck. We even told each other we weren’t going to “try” to take pressure off. Last flow was 5 days late and I got a faint lined test prior to period starting. I’m ovulating next week and would like to know how often you BD around that time? Should we wait a couple days prior to the high day? Help!!!
