I spent two days worrying and googling constantly and am 7 weeks pregnant, can this level of worry harm the pregnancy?

Probably not, but...: Pregnancy and psychiatric illnesses can happen together. Maternal psychiatric illness is not good for a pregnant woman and surely is bad for the baby after delivery. That means a woman with such a condition should first consult with her psychiatrist, her primary care doctor, and her Ob-Gyn doctor before embarking on the pregnancy journey. Anti-anxiety medication can be used during pregnancy.

Probably not: However chronic elevated stress hormones can have an effect on the pregnancy When you're pregnant, chronic stress can increase the chances of having a premature baby (born before 37 weeks of pregnancy) or a low-birthweight baby (weighing less than 5½ pounds). www.marchofdimes.org
