Can covid-19 cause problems for a pregnancy? if a pregnant woman has covid-19 during pregnancy, will it hurt the baby?

Unlikely : There is as of yet little information about how the virus affects pregnancies, the few studies that have done suggest that the virus does not pass from mom to baby during pregnancy. While pregnancy, your immune system is a little weaker, so it is easier for you to catch any kind of illness or have more severe forms of that illness. It does not seem like the virus passes through the breast milk.
