Make sure to not get stressed over it and have fun with it. Make sure your body is healthy and ready for a baby. Ive heard that lifting your legs up to your chest for 15-20 min after intercourse can help. And another thing I would suggest doing is taking vitamins. The healthier u are and the more prepared your body is for a baby the more likely u are to have one!
I would start taking prenatal vitamins and track my ovulation using a kit and try to conceive on those days.
Good luck! :)
