It is disappointing isn't it. How long have you been trying? Just remember also that a couple with no fertility problems still only has a 20% chance of conceiving at each ovulation time. So that is a one in five chance. Which in real terms means it can take up to five months for a couple with no known fertility problems to conceive when trying. It is a hard concept to get used to especially since we all spent our teens thinking if we had sex just once without contraception we were sure to get caught out!! Murphy's Law hey! So don't lose heart yet. Good luck with your efforts.
