During pregnancy skin changes are very common and are not to be of concern. These normal skin changes should not be mistaken for a rash. The normal skin changes in pregnancy are melasma or chloasma, darkening of pre existing moles, linea nigra, stria gravidarum and acne. Pregnancy rash is different from all these regular changes and sometimes might need medical help.
Rashes that occur only during pregnancy are PUPPP (pruritic urticarial papules and plaques of pregnancy), herpes gestationis, impetigo herpetiformis, popular dermatitis of pregnancy, and prurigo gestationis. The non specific rash during early part of pregnancy can be because of hormonal changes and might be on the face and body caused by some irritant like laundry detergent or increased oil or some irritable clothing item.
Prurigo of Pregnancy

In it there are itchy red marks that show up on upper arms, legs, face and most commonly abdomen. These marks are like bumps and are mostly on stretch marks.
Early Pregnancy Rashes
During early pregnancy rashes occur that might be because of hormonal changes in the body. These are normally on face and other parts of the body. Laundry detergents and other irritants are the cause of this kind of rash. Other most affected part by pregnancy rashes are the legs. This is because the legs circulation is affected in pregnancy and combined with hormonal changes the rashes are very common. They are not harmful, but are unsightly to see.
What to Do For Rashes
These rashes that are because of hormonal changes are not at all harmful. The only rash that is of concern is the one caused by cholestasis of pregnancy which causes extreme itching. For regular rash, soap free cleanser should be used and no chemicals should be used to treat it. These rashes normally clear up on their own. Keeping hydrated also helps in clearing away these rashes.
