By this week, fatigue has probably set in again, though maybe not with the same coma-like intensity of your first trimester. Your tiredness is perfectly understandable, given the physical strain you're under and the restless nights of frequent pee breaks and tossing and turning, while trying to get comfortable. Now's the time to slow down and save up your energy for labor day (and beyond).
Most of the time, your cardiovascular and nervous systems are able to adjust to the many changes taking place in your body, but occasionally they can't, and it can make your head spin. Dizziness or lightheadedness can be caused by a variety of things, such as standing up too fast, lying flat on your back, low blood sugar, anemia, and overheating.If you notice itchy red bumps or welts on your belly and possibly your thighs and buttocks as well, you may have a condition called pruritic urticarial papules and plaques of pregnancy (PUPPP for short). Up to one percent of pregnant women develop PUPPP, which is harmless but can be quite uncomfortable. See your practitioner so she can make sure it's not a more serious problem, provide treatment to make you more comfortable, and refer you to a dermatologist if necessary. Also be sure to call her if you feel intense itchiness all over your body, even if you don't have a rash. It could signal a liver problem.
