Hi,
Nitrofurantoin is the generic name of Macrobid and is used to
treat urinary tract infections. It is not expected
to be harmful
to an unborn baby, unless it is
used during the last 2 to 4 weeks of pregnancy. You can first take the antibiotics until the prescribed period then take the pregnancy test after. It is important to finish the course of antibiotics even if symptoms improve before the infection is completely cleared. Take care and keep us posted.
