There are zillions of suggestions out there and nothing is fool proof. My dr told me to get pregnant that I should have intercourse every other day and learn to enjoy it. Also our bodies change as we get older. The first time I got pregnant I was in high school and it was unintended. I was really stressed and it ended in a miscarriage a couple months later. The other three times were deliberate but I was only able to carry one to term.
I think Hamster gave you a good suggestion, the more we fret about it the more stressful getting pregnant becomes. Love making and the birth of a child are both special gifts from God. Perhaps if you keep having regular sex and forget the birth control, I suspect it will happen in due course. After a year or so, you may want to consider consulting a fertility expert, but do not be in a great hurry,

Meanwhile I send you my love and above all my hopes and prayers for the best
