I have been trying to get pregnant its been 7 months with out using any kind of protection and still no luck, what could be the problem ?

You are normal: Since there is only a 15 percent conception rate per cycle, 85 percent of couples will conceive after a year of trying. This is why most gynecologists will recommend waiting a year to be evaluated. Use ovulation kits to help pinpoint ovulation. Avoid ejaculation 2-3 days prior to ovulation. Eat healthy. Relax.. Enjoy trying to get pregnant.
