I am always encouraged anytime a pregnancy is established because it has tested many aspects of reproduction. Most who have become pregnant and have miscarried will eventually establish a successful pregnancy. Individuals should seek help in outlining a diagnosis and therapeutic intervention if a pregnancy has not been achieved in 12 months. If menstrual cycles are greater than 35 days in length, or there is another cause of known infertility, help should be sought sooner. It can sometimes be helpful to use an ovulation predictor kit and temperature tracking to more closely time intercourse to ovulation.
Male infertility is pretty much a thing of the past due to modern technology.
In other cases, we can inject a single sperm into the egg, which gets around many of the problems. In the case of a blocked tube, we can actually remove sperm directly from the testis to bypass any tubal problems. Miscarriage is a way that nature has of protecting itself from deformities or other kinds of problems. Most causes of miscarriage are almost never due to a situation caused by anything that the mother did. The future is bright even with several miscarriages, that is, it is still possible to have a successful pregnancy in the future.
