Did we BD enough?

Hello ladies, we've been TTC for 3.5 years now, I have endometriosis and low AMH for my age (29). Hubbys results are very good (36). We're now waiting for our first IVF starting sometime in October. Still not losing hope to conceive naturally as my endo and cysts are not in a very bad state at the moment. So this cycle we BDed 5 times, Clearblue showed positive yesterday and we BDed last night. Now I am wondering if we should BD again tonight or do you think we've done what we can? Considering my bbt jump yesterday ? Thanks a lot for your help!
