Relax and try not to thing about it
Try and reach orgasm, i have read it helps open the uterus therefore helping spermy make his way to miss egg!
When it doesnt happen try not to get stressed, stress can affect the baby making hormones therefore not allowing you to get preggo.
Have sex for fun not for baby making, make it fun get lingerie and explore different positions.
Kepp telling yourself it WILL happen.
good luck, im still waiting for my bfp but trying my hardest not to stress
