This is one of those questions that’s impossible to answer. We can regale you with stats and percentages referring to what usually happens at around what time frame, but the reality is that every woman is different, and that a woman in her 40’s might have an easier time getting pregnant than a woman in her 20’s. So rather than go on about fertility rates, we’ll just say that if you’re beginning to chart your ovulation cycles and have a general sense of when you’re at your most fertile, keep on trying (and try to ENJOY it if you can.) If you’ve tried for one year without success, you may want to start seeking help from a fertility specialist.
