It's ironic, really, how many of us spend so many years trying not to get pregnant, only to discover that when you do actually try to have a baby, it might not be quite as easy as you thought it would be.

In fact, according to a recent article in Business Insider, many women in their 20s and 30s assume that they can get pregnant whenever they want, and therefore figure that when they decide to start trying for a baby, they'll get pregnant right away. The reality, however, might not be quite that straightforward. This is what fertility expert Dr. Shruti Malik had to say:

"Most couples will conceive in about six months or less," Malik said. "So it's interesting, because I have a lot of patients who spent a good portion of their adolescence trying to prevent pregnancy, and then later find out that it's more difficult than one would necessarily presume."

In fact, according to the expert, couples who have no history of infertility, and are having regular unprotected sex, "only" have a 15% to 20% chance of conceiving per cycle.

"So if you were to consider all of those, if you have six cycles of doing that, most couples will conceive in that six-month window," Malik said.

If, however, you and your partner have been having regular unprotected intercourse without getting pregnant for 12 months, Malik thinks you should consider seeking some help.

"If a women trying to get pregnant has not conceived in that window, there is a higher likelihood that there may be other factors that are contributing to that couple's difficulty in conceiving. And at that point in time, it warrants seeing a physician or fertility specialist."
