LH Surge - how many times should I have sex?

Hi! Just got a positive LH Surge on my clearblue easy digital ovulation kit this morning. We had sex last night. Now I'm wondering when to have sex again and how many times. Should I have sex again this morning or just wait until tonight and just have sec at night. Is 2x /day too much. When I conceived my first babe we got preg from having sex every other day, but we didn't use a kit. Any advice on the timing now? Thanks in advance!
