How old are you and how long have you have and the bf been thinking of ttc?
first count 14 days from the first day of your period that is your peek ovulation time and also have sex in a position that him penis goes in the furthers into your vagina because then the sperm has to travel less. also if you can prop yourself up at the hips after having sex to help the sperm a bit. also if you can help it don't go to the bathroom right after having sex. (as long as you know you wont get an infecting which some women do). other then that have fun.
