Conception - faulty implantation?

I am a mother of two and I have been trying for a baby for two years. Prior to my period (5-7 days), which is regular, I feel nauseous, have dry mouth and tender breasts. I feel that I am pregnant but I always get my period. When I know that I have not conceived I do not get these symptoms. Is it possible that conception is taking place and not implantation?

Conception takes place in the Fallopian tubes and the fertilised ovum implants in the wall of the womb a few days later. Your question suggests that your symptoms indicate that you may have conceived but then implantation did not occur. However, symptoms of pregnancy develop after implantation occurs and are a consequence of the hormonal changes that are initiated by implantation. In other words, pregnancy related symptoms are a consequence of implantation not conception. The premenstrual symptoms you describe may simply be from PMS (premenstrual syndrome). Since you have been trying to conceive for two years without success it may be worthwhile discussing the matter further with your GP. Your level of fertility, or that of your partner can alter over time.
