Pregnancy: Conception – Maternity – Trimester
No symptoms during pregnancy and whether it is normal

No symptoms during pregnancy and whether it is normal

Why some pregnancies have few or no symptoms Classic early pregnancy symptoms are often taught as if they happen to everyone, but in real life they are not universal. Nausea, breast tenderness, fatigue, food aversions, and urinary frequency are common, yet some people experience very mild versions of them or none at all. That can […]

Increased saliva and drooling in pregnancy

Increased saliva and drooling in pregnancy

What increased saliva and drooling in pregnancy means Excess saliva in pregnancy is often described as hypersalivation, sialorrhea, or ptyalism gravidarum. In practical terms, it means producing or noticing enough saliva that swallowing feels constant, saliva pools in the mouth, or drooling occurs during the day or at night. The symptom often appears early in […]

Gum bleeding and pregnancy gingivitis

Gum bleeding and pregnancy gingivitis

Why pregnancy gingivitis happens Pregnancy gingivitis is an inflammatory response of the gums that becomes more likely during pregnancy because of hormonal shifts, especially increases in estrogen and progesterone. These hormonal changes can alter the microenvironment of the gingival sulcus and make the tissues more vulnerable to the inflammatory effects of dental biofilm, even when […]

Increased heart rate and palpitations during pregnancy

Increased heart rate and palpitations during pregnancy

Why the heart often feels faster in pregnancy Pregnancy places extra physiologic demands on the cardiovascular system. Blood volume rises, cardiac output increases, and the autonomic nervous system adapts to support the uterus, placenta, and developing fetus. For many people, that translates into a resting pulse that is higher than it was before pregnancy and […]

Hair and nail changes in pregnancy

Hair and nail changes in pregnancy

Why pregnancy can change hair and nails Hair and nails are both keratinized tissues, so they respond to the shifting endocrine and metabolic environment of pregnancy. Rising estrogen tends to prolong the anagen, or active growth, phase of hair follicles. In practical terms, fewer hairs are pushed into the resting telogen phase at any one […]

Changes in smell and taste during pregnancy

Changes in smell and taste during pregnancy

What changes are actually reported? Pregnant people often describe a heightened or distorted sense of smell, but the scientific picture is more nuanced. A recent systematic review and meta-analysis found that odor identification tends to be poorer during pregnancy, while odor intensity is rated as stronger in the second and third trimesters. The same review […]

Stretch marks and skin itching in pregnancy

Stretch marks and skin itching in pregnancy

What stretch marks in pregnancy are Stretch marks, also called striae gravidarum, are linear marks that commonly appear as the abdomen enlarges, although they may also develop on the breasts, hips, buttocks, and thighs. They are not a sign that anything is “wrong” with the pregnancy. Instead, they reflect the skin’s response to rapid expansion, […]

Melasma and darkening of skin during pregnancy

Melasma and darkening of skin during pregnancy

What melasma is and why pregnancy can trigger it Melasma is a common form of acquired hyperpigmentation, usually seen as symmetric brown or gray-brown patches on the cheeks, forehead, upper lip, nose, or chin. It is not an infection, and it is not dangerous in itself. The condition is multifactorial: pregnancy-related hormonal shifts, ultraviolet exposure, […]

Vivid dreams and sleep changes in pregnancy

Vivid dreams and sleep changes in pregnancy

Why dreams often become more vivid in pregnancy Dreaming is not simply a random mental event; it is shaped by sleep stage, arousal threshold, and how often sleep is interrupted. Pregnancy can shift all three. Research synthesis suggests that pregnant women tend to report more dreams and nightmares, and that stronger dream recall is often […]

Least reliable pregnancy symptoms explained

Least reliable pregnancy symptoms explained

Why some pregnancy symptoms are so unreliable The least reliable pregnancy symptoms are usually the ones people feel most strongly: nausea, fatigue, breast tenderness, bloating, and cramping. They are unreliable because they are nonspecific; in other words, they occur in pregnancy but also in many other settings. Hormonal shifts in the luteal phase, premenstrual syndrome, […]
