Advice please! To BD or not to BD!

Rebecca • One of each 💙💖
Ok so have been using OPKs for 15 days and got my first positive today. Have done the BD the last 4 days in a row but not sure now whether to leave it tonight and go again tomorrow ready for ovulation, or to go again tonight? I do know that they advice every other day to let the sperm build up... Any thoughts would be great thanks!
