Pregnancy brings a host of changes to your body. Some, including morning sickness and your swelling abdomen, are well-known enough to be expected by every new mother-to-be. Others come as an unhappy surprise, such as rapidly-growing facial and body hair or pimple-like growths on the chest. Almost immediately after conception, your body starts to produce pregnancy-related hormones. It s sometimes possible to realize you re pregnant only a few days after conception, because the sudden increase in hormones makes your breasts and nipples unusually sensitive. These increased levels of hormones can also have a number of effects on your skin. They re the source of the glow on your skin, for example. Unfortunately, hormones also stimulate changes that are less welcome.
