Hello, I have gone through your query and understood the concern. Use of contraception, especially in the manner adopted by you, does not cause delay in achieving a natural pregnancy in ordinary circumstances. Use of hormones can delay return of ovulation and hence cause a delay. As you did not use any medication, there is no such worry. Please try sincerely for at least six months before going for further help. Try to have regular intercourse, at least on alternate days during the fertile period of your cycle. Hope I have answered your query. Take care.
