For most women, pregnancy is suspected when the symptoms of early pregnancy develop—these include breast soreness or tenderness, fatigue, nausea, and missed menses. Human chorionic gonadotropin (hCG) is first detectable using sensitive tests in the urine and blood of pregnant women 8–10 days after conception (day 22–24 of a 28-day menstrual cycle). Concentrations of hCG rise rapidly in early pregnancy, peak at 9–10 weeks, and decline thereafter to a nadir at 20 weeks. Understanding embryo-foetal development and maternal physiological accommodation to pregnancy is required for the optimal management of pregnancy in women with autoimmune diseases. This chapter reviews the important developmental and physiologic aspects of normal pregnancy and both common and unique obstetric complications associated with selected rheumatic conditions.
