TTC baby #1. When is a good time to BD?

Amanda • We are a beautiful family of three and are hoping to expand that sometime this year or next. No rush just enjoying life with our daughter!!
Was wondering what couples out there have done. Is having sex in the morning better or right before bed? We normally BD right before we fall asleep and on the weekends sometimes it is in the morning or randomly in the afternoon. Was wondering what works for other couples? We are just trying to have fun with this! Opinions? Morning or at night?
