LINEA NIGRA
LINEA NIGRA includes the darkening of what body parts?
- nipple
- areola
- lower midline of the abdomen
- axilla
- neck

When the patient had already delivered, the stretch marks will appear as a silvery scars and they also become discolored after ______ weeks of puerperium period.
4-6 weeks
Are vascular, stellate marks which result from high levels of circulating estrogen and which blanch when compressed;
SPIDER TELANGIECTASIA
Associated sign together with spider telangiectasia
palmar erythema
Thermal signs are perceptible elevation of temperature longer than?
3 weeks
Thermal signs are attributed to the thermogenic effect of?
progesterone
PROBABLE EVIDENCE OF PREGNANCY
