Ttc#2

Anyone trying to concieve and want a buddy .. I'm trying for my second child now that my first (a boy) has turned 3yrsOld old. I am on my 3rd month of following ovulation and I usually do the deed on 2 Days before, a day before and day of ovulation. Is this the best way of ttc?? I know I ovulate every month on day 15 of my very regular 28 day cycle. Advice always appreciated!!!
