Frequency of sex when ttc

I just started my first proper period after stopping the pill -not including the withdrawal bleeding that occurred a few days after stopping.

I took ovulation tests frequently and never got a positive test. It did get darker but never the same darkness at control line.

I’m unable to test multiple times a day due to work so I figured a plan for this cycle would be to try to have sex with my partner every night once my period stops. We are both young and are able to have sex every night so it is a sustainable goal for us.

Has anyone else used this method?

Also my period was late this morning by 2 days so I wouldn’t even know when to start testing for ovulation as my cycle lengths may be different now.
