Sleep Problems Women who are pregnant often experience sleepless nights and daytime fatigue in the first and third trimesters of their pregnancy. During the first trimester frequent trips to the bathroom and morning sickness may disrupt sleep. Later in pregnancy, vivid dreams and physical discomfort may prevent deep sleep. Fatigue during the first trimester of a pregnancy is likely due to changing levels of hormones, such as progesterone. Toward the end of a pregnancy, some women find it difficult to sleep because they are uncomfortable due to the size of their abdomen.
Some women are too excited, anxious or worried about becoming mothers to sleep well.
Other women who are pregnant complain that vivid dreams prevent them from getting restful sleep. Sleep apnea especially if it's severe and causes your blood oxygen level to drop during sleep, is a risk to the fetus. Exercise during the day should help too. Expecting mothers may find it more comfortable to sleep on their side, with pillows supporting their head, abdomen and topside knee. Women who are pregnant should not take sleeping pills or herbal sleeping remedies without talking with their health care provider first.
