TTC, should we bd every day or every other day?

I have heard good and bad points to both ways with regards to bd when TTC. Does anyone know if it is really worse if you do it every day? I have heard that makes the sperm concetration lower but it still seems to me that the more often the better, no? What do you guys think? We are TTC 4 months after a miscarriage so I would really appreciate helpful advice. One friend told me to do it "every day for 10 days around your fertile period." Any thoughts? Thanks so much and baby dust to all! :)
