Heightened sense of smell

Peeu that stinks! Are you noticing the odor of the trash can from two rooms away or does the smell of chicken frying up in the pan make you feel ill? This is one thing women may notice before they even realize theyre pregnant. Pregnant womens noses dont get any bigger and there arent actually any changes that we know about that occur within the olfactory system, but none the less, its a symptom that lots of newly pregnant moms experience. Were not entirely sure what causes this symptom but it may have something to do with the increase in estrogen levels.
